# How does a single acting reciprocating pump work?

## How does a single acting reciprocating pump work?

Single-acting reciprocating pump: This has one suction valve and one discharge valve. When the piston is moved backward, suction happens and when it moves forward, the delivery valve opens up to discharge the liquid. Thus it requires two inflow pipes and two outflow pipes.

What is a single acting reciprocating pump?

Single-acting reciprocating pump consists of a piston of which only one side engages the fluid being displaced. Double-acting reciprocating pump engage with both sides of the piston, each stroke of the piston carries out both suction and expulsion at the same time.

### What is the working of reciprocating pump?

Introduction of Reciprocating Pump: Reciprocating Pump is a Positive Displacement type pump that works on the principle of movement of the piston in forwarding and backward directions whereas the Centrifugal pump uses the kinetic energy of the impeller to supply the liquid from one place to another place.

How does a double acting reciprocating pump work?

The pump works on the principle of reciprocation of the piston and the cylinder. Creation of vacuum resulting in suction and compressing of the water resulting in discharge is the basic principle of operation. Both the strokes are effective and hence it is known as a Double Acting Reciprocating Pump.

#### What are the advantages of reciprocating pump?

• Reciprocating pump can deliver the required flow rate very precisely.
• It gives a continuous rate of discharge.
• It can deliver fluid at very high pressure.
• No priming is needed in the reciprocating pump.

What is difference between reciprocating pump and centrifugal pump?

The reciprocating pump provides a nearly constant flow rate over a wider range of pressure; the centrifugal pump gives uniform pressure over a range of flow, then it drops dramatically as the flow rate increases. On a reciprocating pump, fluid viscosity has little effect on the flow rate as the pressure increases.

1) Reciprocating pump can deliver the required flow rate very precisely. 2) It gives a continuous rate of discharge. 3) It can deliver fluid at very high pressure. 4) No priming is needed in the reciprocating pump.

What is the disadvantages of reciprocating pump?

Disadvantages of Reciprocating Pump: 1) The pump is very costly (Capital cost is high). 2) Viscous liquids are difficult to pump using a reciprocating pump. 3) The maintenance cost of the pump is very high as there is a large number of parts. 4) The flow rate is less.

### Which type of pump is more efficient?

Where different pump designs could be used, the centrifugal pump is generally the most economical followed by rotary and reciprocating pumps. Although, positive displacement pumps are generally more efficient than centrifugal pumps, the benefit of higher efficiency tends to be offset by increased maintenance costs.

Why do we use reciprocating pump?

Reciprocating pumps are used where a precise amount of fluid is required to be delivered, also where the delivery pressure required is higher than can be achieved with other types. The fluid is moved by the means of a piston that travels in a cylinder.
