Type Of Pump

Pumps Can Be Broadly Classified Into The Following Types:

1. Volumetric

The positive displacement pump relies on the reciprocating or rotating motion of the working element in the pump cylinder to make the working volume increase and decrease alternately to realize the suction and discharge of the liquid. The positive displacement pump whose working element performs reciprocating motion is called a reciprocating pump, and the one that performs rotary motion is called a rotary pump.

2. Dynamic

Relying on the force of the rapidly rotating impeller on the liquid, the mechanical energy is transferred to the liquid to increase its kinetic energy and pressure energy, and then most of the kinetic energy is converted into pressure energy through the pump cylinder to achieve transportation. Power pumps are also known as impeller pumps or vane pumps. Some power pumps have both the main impeller and the auxiliary impeller, and the centrifugal pump is the most common power pump.

3. Diaphragm

Diaphragm pump, also known as control pump, is the main type of actuator. By receiving the control signal output from the modulation unit, the fluid flow is changed with the help of power operation. Diaphragm pumps generally consist of actuators and valves. Using compressed air as the power source, it can absorb all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids.

A pump is a machine that converts mechanical energy into liquid energy to transport liquid or pressurize liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, so that the liquid energy increases. The pump is mainly used to transport liquids such as water, oil, acid-base liquid, emulsion, suspension emulsion and liquid metal, and can also transport liquid, gas mixture and liquid containing suspended solids.
