The present invention is related to fluid pumps. In particular the invention is related to centrifugal pumps used for pumping water or liquids of similar viscosity or indeed other fluids such as oils, mud slurries, and wet concrete.
A conventional centrifugal pump works with an electrical power driven motor connected to the pump on its driving end. The non-driving end of a conventional pump typically has a cooling fan which is used for continuous cooling of the motor to avoid overheating of the motor in continuous application. The driving end of the motor has an extended shaft which is connected to a impeller housing also termed as pump housing which houses an impeller which is either of a closed or an open type.
In the monoblock type arrangement, the impeller housing is an integral part of the motor whereas in the non-monoblock arrangement, the impeller housing is separate and connected to the motor shaft by means of a coupling. A monoblock type is generally meant for light texmo monoblock pump meaning application whereas for heavy and continuous duty, the non monoblock type is preferred.
A centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure and flow rate of a fluid. Centrifugal pumps are the most common type of pumps used to move liquids through a piping system. Centrifugal pumps are typically used for large discharge through smaller heads at the upstream ends. Losses of a typical centrifugal pump are internal and external type. Texmo monoblock pump meaning types of internal losses are known including the hydraulic losses or blade losses by friction, leakage losses, friction losses ate the external walls of wheels.
The external losses include sliding surface losses, air friction losses at the clutches, and energy consumption of directly propelled auxiliary machines. While it is known that several attempts have been made and continue to be made to minimise these losses, the percentage improvement by minimising these losses is small. There is therefore a need to provide an improved pump that will improve the output more than that obtained by improvement in the above mentioned aspects.
Any continuously operating pumps are expensive to run and maintain. There's therefore a need to provide improved pumps that will be more economic to provide and maintain. Accordingly, one of the objects of the present invention is to provide a centrifugal pump that is more economic to provide, operate, and maintain.
A further objective of the present invention is to provide a centrifugal pump that uses less resources per unit volume of the pumped fluid than the conventional pumps. The present invention discloses an improved centrifugal pump that provides nearly double the output measured in terms of the volume of liquid pumped per unit time than a conventional pump of the same HP rating for a proportionately less increase in the power consumption.
The improved pump operates on a single motor and has two suction mouths and two delivery ports provided on the impeller housing. The improved pump sucks up the water to be pumped through the two suction mouths and is pumped out via the two outlet ports after passing through a novel arrangement of motor with a dual end shaft, impellers and impeller housings, cooling fans, bearings.

The present invention comprises a modified centrifugal pump. As shown in Figure 1 and 1A, the conventional centrifugal pumps have a single motor, single suction port and a single delivery port.
A central shaft emerging from a rotor the prime mover drives the impeller that is enclosed in a housing. There are cooling fans or other suitable mechanisms to cool the moving parts which need to be cooled as they heat up during the texmo monoblock pump meaning. A typical conventional pump has a single shaft that ends in the rotor motor.
The other end of the shaft is connected to an impeller that rotates to create suction which draws texmo monoblock pump meaning which when passed over an impeller is sent through the outlet or delivery port under pressure and at a velocity.
The shaft also drives the cooling fan. The present invention comprises a modified centrifugal pump 1A comprising a single motor 2 a single shaft 2Aand a first impeller 4A and a second impeller 4B which are respectively housed in a first and a second impeller housing 5A, 5B. All other parts that are necessary for working of a typical centrifugal pump are provided in a modified form as appropriate.
This will be apparent from the forthcoming description. As seen from Figure 2, the pump of the present texmo monoblock pump meaning has two suction ports termed as a first suction port 3A and a second suction port 3B and two delivery ports termed as first delivery port 9 A and a second delivery port 9B and a single motor 2.
The water taken in via two suction ports 3A, 3B enters the volute or casing through the respective suction mouth 3C, 3D of the respective impellers 4 A, 4B. The impellers 4 A, 4B which rotate with the help of the energy provided by an energy source such as an electric motor, throw out the water through the two delivery ports 9 A, 9B that are provided on the impeller housings 5 A, 5B. In the process, texmo monoblock pump meaning water has gained sufficient head to reach a certain height.
It can be seen from Figure 2A that the pump of the present invention comprises what can be termed as 'two halves' which are preferably bilaterally symmetrical in the way which its several parts are arranged. Figure 2A shows an exploded view of the present invention and the direction of rotation of the vanes 4E and Figure 2B shows the modified shaft of the present invention. The shaft 2A has been modified such that it is placed securely inside the motor 2 and either end of the shaft is modified such that impellers 4A, 4B may be mounted on the ends in a manner known to a person skilled in the art.
It is clear from this figure that necessary parts required for making of a functional centrifugal pump, such as, but not limited to, impellers, housing, bearings, cooling fans are provided at each end of the shaft to facilitate this. Figure 3 texmo monoblock pump meaning the texmo monoblock pump meaning motor 2 used in the present invention. It can be seen that it comprises texmo monoblock pump meaning single rotor but it has been texmo monoblock pump meaning such that the shaft 2A extends out on either side of the motor.
One of the inventive features of the present invention is that, unlike the conventional pumps, impellers 4A, 4B are provided at each end texmo monoblock pump meaning the shaft 2A. This allows water to be sucked in on each end of the shaft 2A. Another feature of the present invention is that the impellers are modified such that they rotate in the same direction as each other, as illustrated by directional arrows placed around the shaft axis in Figures 2A and 3.
In other words, the impellers 4A, 4B of the present invention are designed and configured such that when viewed from any one side along the axis, both impellers rotate in the same direction. Specifically, this means that the water suction ports 3A, 3B and shaft mounting ports of the impeller for right and left side impellers are provided on opposite faces in respect of the direction of rotation of each impeller see figures 4, 5 and 6.
In other words, if one impeller is viewed as a 'right hand' impeller in terms of the direction of its rotation and that of the water flowing out, the other impeller would be termed as a 'left hand' impeller. Figure 4 shows a view of an impeller housing 5A and a delivery port 9 A. As can be seen from Figure texmo monoblock pump meaning, the relative arrangement of the impeller housings 5 A, 5B, placed texmo monoblock pump meaning by side for illustration purposethe delivery ports 9 A, 9Band the impeller face plates 4D mirror each other when placed side by side.
Texmo monoblock pump meaning is also evident from Figure 6, which show the modified impellers 4A, 4B of the present invention, placed side by side for the purpose of texmo monoblock pump meaning, and which are placed on either side of the shaft 2 Texmo monoblock pump meaning such that the impeller hubs 4F are placed on the that surface of the respective impellers the face plate, see Figure 7 which allow water to be thrown out of the delivery ports 9 A, 9B in the same direction when the impellers 4A, 4B are placed in their respective places on either end of the shaft 2A.
Figure 8 shows some of the several impeller designs currently used for centrifugal pumps. The impellers used in the invention may be modified from any of these or other similar impellers, modifications being those described in this document.
In particular, the hubs, the suction mouths, vane directions of the impellers of the present invention are so oriented and located as to facilitate entry and exit of water from both ends of the shaft. The impellers suitable for the invention may be of radial-flow, axial- flow, or mixed-flow type. They may be closed or open, or semi-open or vortex type.
Some of the conventional vanes are shown in Figure 8, which can be modified for use texmo monoblock pump meaning the present invention in accordance with the guidelines provided earlier.
Impeller housings or casings suitable for the invention are typically of two types, namely volute texmo monoblock pump meaning circular. Either type of casing may be used in the pump of the present invention.
The impellers are fitted inside the casings. It is well known that a volute casing builds a higher head but have low capacity whereas the circular casings are used for low head and high capacity. The casings texmo monoblock pump meaning be designed either as solid casings or split casings. Solid casing implies a design in which the entire casing including the discharge nozzle is all contained in one casting or fabricated piece.
A split casing implies two or more parts are fastened together. Pumps of virtually any capacity may be built using the disclosure made herein. As in the case of conventional pumps, the capacity of the texmo monoblock pump meaning action pump disclosed herein depends on a number of factors such as the character of the texmo monoblock pump meaning liquid - its density and viscosity, pump size and its inlet and outlet sections, the impeller size and the rotational speed of the impeller, texmo monoblock pump meaning and shape of cavities between the vanes, and the pump suction and discharge temperature and pressure conditions.

It is evident from the above data that an Apex dual pump of the present invention with 10 hp rating:.
The pump of the present invention consumes The power used per litres by the pump of the present invention is 0. The time required for delivering a unit volume of liquid lkL in 42 seconds is substantially less with the pump of the present invention than the conventional pump which takes 71 seconds to deliver litres of water. In terms of the material costs, the existing pump is more economical to manufacture as it uses a single rotor and a motor. Although the above example relates to fluids of viscosity similar to water, the pump of the present invention is useful with other fluids The pump of the present invention is useful for pumping all types of fluids including oils, mud slurries, and wet concrete.
