Apakah itu pompa reciprocating ?

Merupakan pompa bolak-balik yang dirancang untuk menghasilkan kapasitas yang cukup besarUmumnya menggunakan head yang rendahDigunakan pada perbedaaan ketinggian yang tidak terlalu besar antara suction dan discharge

Prinsip Kerja

Fast moving air formed by releasing high pressure air through a slit is discharged adjacent a surface, and drags ambient air along with it. The higher the pressure of the primary air supply, the worse the efficiency

The liquid enters a pumping chamber via an inlet valve and is pushed out via a outlet valve by the action of the piston or diaphragm.

Pump is self priming as it can draw liquid from a level below the suction flange even if the suction pipe is not evacuated

The diaphragm pump is an offshoot of a plunger pump. Because of the risk that contamination could travel between the plunger and the cylinder, the diaphragm is safer for microbial processing. This applet is crude but shows how a reciprocating piston (plunger) pump works. The flywheel that moves the plunger can attach the arm to the plunger at various points to change the amplitude of the stroke and thus the pumping rate. The pumping rate can also be changed with a different rotational speed, but variable speed motors or mechanical means of changing rpm are expensive

PISTON PUMP A piston pump can be based on a single piston or,

more likely, multiple parallel pistons.   The pistons are reciprocated using cams or crankshafts.   The stroke is generally adjustable.  This type of pump can deliver heads of up to 1000 bar.   The largest sizes of piston pumps can deliver flows of 40m3 /hr. In practice these pumps are more likely to be used for metering low flow rate fluids at more modest pressures in laboratories and chemical process plants.   Piston pumps are not generally suitable for transferring toxic or explosive media.

Diaphragm Pumps

There are two types of diaphragm pumps : The hydraulically operated diaphragm

metering pumps The air actuated type.

KELEBIHAN & KEKURANGAN

Very efficient and are suitable for very high heads at low flows

The reciprocating pump is not tolerant to solid particles

Delivers a highly pulsed flow This feature is not required for safety for

the air operated
