How many types of pumps

In centrifugal pumps the direction of flow of the fluid changes by ninety degrees as it flows over impeller, while in axial flow pumps the direction of flow is unchanged. Both types are designed to move water from one place to another continuously. A centrifugal water pump uses a rotating impeller to move water into the pump and pressurize the discharge flow.

The three common types of rotary pumps are rotary barrel pump , super rotary pump and professional rotary pump. Asked in Water Pumps , Mechanical Engineering , Hydraulics What are different types. They are also used for chemical transfer, de-watering underground coal mines, food manufacturing or where the liquid being pumped has a high solids content or high viscosity.

But selecting the type of pump can be difficult as it mainly depends on respective requirements. Here are the two types of pump: 1. Positive Displacement Pumps. Dynamic Pumps: This pump is also known as Kinetic pump. In this article we will learn about the working of various types of rotary pumps, i. We will also learn how is the working of screw pump different from that of other types of pumps.

The centrifugal pump is a type of pump that uses a swirling motion to pump liquid. Asked in Mechanical Engineering , Machinery and Tools What are different types of vanes used in centrifugal pump ?

Unlike the centrifugal pumps , these types of pumps are only classified into main types. Mixed Flow Pumps are medium flow, medium pressure pumps which push fluid out away from the pump shaft at an angle greater than 90°. A guide to industrial pump types - including description, applications use flow rate ranges, horsepower ranges, advantages and much more. A submersible sump pump can be placed below the water line.

A floor model sump pump, on the other han sits at floor level. Types of Heat Pumps - Many geothermal systems use an open loop well system for a geothermal heat pump system. One well is used to dump the water from the condenser and the other well is a feeder well.

Types and features of multiphase pumpsEdit. The twin-screw pump is constructed of two inter-meshing screws that move the pumped fluid. There are two wells drilled. Twin screw pumps are often used when pumping conditions contain high gas volume fractions and fluctuating inlet conditions.

Four mechanical seals are required to seal the two shafts. But the pressure required for the mobile phase to flow is very high. So pumps able to generate such high pressure are needed in HPLC.

Shown above is a cross section through a vertically mounted centrifugal pump. Water is led to the suction eye of the rotating impeller. The water gains energy by the centrifugal action of the pump and is discharged to the volute outlet casing.

Plunger type (with inline jerk) 2. Vane pump (with rotary pump) 3.
