have a sealless design; they do not have cups,
packing or mechanical seals. They are used for flow rates
from fractional GPM up to 45 GPM for discharge pressures from 50
to 3000 PSI. Hydra-Cell pumps are ideal for pumping
cryogenic, very hot, abrasive and reclaimed fluids that
compromise traditional "sealed pumps".
Hydra-Cell™ pumps are positive displacement and unlike
centrifugal, gear, air operated diaphragm and progressing cavity
pumps, ours operate at ≥90% efficiency. Furthermore, they
are sealless, meaning they have no cups, packing or mechanical
seals, and this provides you with long reliability and minimal
Hydra-Cell™ Pumps - Right For Your
Since Hydra-Cell™ pumps are sealless and
positive displacement, our applications generally fall into one
of three categories:
Difficult to pump fluids:
These range from reclaimed water, recycled machine tool
coolant, acids, slurries, very hot or very cold fluids,
viscous and shear sensitive fluids. Fluids like this
tend to stick to the sealing surfaces of other pumps causing
accelerated wear and leakage. The operating pressures
range from just a few PSI to several hundred PSI.
Atomizing of water, airless paint spraying, high pressure
machine tool coolant pumping, Reverse Osmosis and high
pressure cleaning applications such as centralized service
water systems, paper mill felt cleaning and steel mill
hydraulic descaling are all examples of high pressure
Hydra-Cell's meet API 675 metering pump standards in terms
of linearity, repeatability and steady-state accuracy.
They are an especially cost-effective pump for metering
applications in excess of 60 GPH.
The unique design of the Hydra-Cell™ Pump is
not dependent on the fluid being pumped for internal
lubrication. In-fact, all the bearings and moving parts are
isolated from the fluid being pumped. This is why we can
reliably pump chemicals, abrasives, slurries, viscous products,
seawater, re-circulated water and many other fluids, either hot
or cold. Our pumps are available with both metallic and
non-metallic pump ends and can be direct driven with electric,
pneumatic or hydraulic motors.

- They're Sealless!
There are no cups,
packing or mechanical seals in Hydra-Cell™ Pumps. All
the sliding and rotating parts are isolated from the pumped
fluid. This enables you to pump solids laden (dirty)
fluids, very hot or cold fluids and also lets you run the
pump dry! Your piston, plunger, gear and progressing
cavity pumps will not hold-up to tough fluids as well as
Hydra-Cell's™ have up
to 30% fewer parts than other common industrial pumps.
Less parts equates to less maintenance and downtime - which
can be very costly. If you're having mechanical
seal problems or replacing stators and rotors on a regular
basis you ought to really consider switching to Hydra-Cell™
- Smooth, Consistent
Flow. Since Hydra-Cell's™ are
positive displacement pumps, each rotation displaces a fixed
amount of fluid. Our pumps are often used in
conjunction with variable speed motor controls as metering
pumps - reliably dosing or transferring fixed amounts of
fluid in a process. Unlike piston pumps and other
reciprocating pumps, Hydra-Cell's™ provide a smooth,
virtually pulsation-free flow rate. With the exception
of certain membrane and plastic piping applications,
pulsation dampeners are not required.
