Apakah itu pompa reciprocating ?

 Merupakan pompa bolak-balik yang
  dirancang untuk menghasilkan kapasitas
  yang cukup besar.
 Umumnya menggunakan head yang
  rendah.
 Digunakan 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.
Jenis-jenis pompa reciprocating

Piston pump
Diaphragm pump
                 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.
