Reproducible
Metering |
|
|
|
Precise metering at high pressure is attained
by a positive displacement, reciprocating piston assembly. The
piston is driven by a constant speed motor via a specially contoured
cam. The cam profile is designed so the piston rapidly intakes and
delivers a smooth, constant volume of fluid to the end of the piston
stroke. Thus, motor efficiency is maximized and pulsation minimized.
|
|
|
|
| Reproducible metering is
attained by precise control of the piston's stroke length and rapid
response check valves. The piston's stroke length is fixed by
a precision micrometer which is simple to use and assures
reproducible metering. The inlet and outlet check valves
regulate flow direction. |
 |
|
|
|
|
The piston assembly is uniquely designed to
permit an even application of the force driving the piston - a detail
which helps to insure exact, reliable liquid transfer and extended seal
life.
|
|
|
|
Corrosion
Resistant |
|
|
|
The materials in the liquid end of Eldex pumps
are carefully chosen for corrosion resistance. The piston is
sapphire, and the inlet and outlet valves incorporate sapphire seats and
ruby balls.
|
|
|
|
 |
The standard piston seal
material is an ultra-high molecular weight polyethylene with
excellent chemical compatibility characteristics. For
specialized applications a graphite fiber reinforced PTFE may be
substituted. |
|
|
|
|
The liquid end
housing is made of type 316 stainless steel because of its superior
resistance to corrosion. |
|
|
|
In applications requiring the use of extremely
corrosive materials, CTFE or PEEK versions of the liquid ends are
available.

Reliable
Design |
|
|
|
The compact pump housing, unique piston
assembly and many other features demonstrate our dedication to building
precision metering pumps made to last. We know they last because
users all over the world tell us time and again that their Eldex pumps are
still performing after years of continuous use.

Choose
a model meeting your requirements:
|
|
|
|
All ReciPro liquid metering pumps operate most
efficiently in the upper range of their flow rate capacity, so it is
always a good idea to choose a model you will use as close as possible to
its maximum.
