Reciprocating Pumps - Classification According to the number of cylinders

As the name suggests, a reciprocating pump having only one cylinder is known as Single Cylinder Reciprocating Pump.

Classification According to THE NUMBER OF CYLINDERS


1. SINGLE CYLINDER RECIPROCATING PUMP

As the name suggests, a reciprocating pump having only one cylinder is known as Single Cylinder Reciprocating Pump. Fig. 1 shows a Single Cylinder Single Acting Reciprocating Pump. Note that a single cylinder pump may also be a double acting reciprocating pump.

 

2. DOUBLE CYLINDER RECIPROCATING PUMP

See Fig. 3. A Double Cylinder (Single Acting) Reciprocating Pump is the one which has two single acting cylinders. Each cylinder is provided with a suction pipe fitted with a suction valve and a delivery pipe fitted with a delivery valve.

Also, there is a separate piston for each of the two cylinders as shown. Both the pistons are simultaneously driven from cranks set at 180°.
