Peristaltic Pumps for Industrial Applications
are available with hose sizes from ½" to
6" to provide flow rates from 18 GPH to 211 GPM for transferring
fluids at pressures up to 217 PSI. Since there are no seals,
valves, dead corners or glands peristaltic pumps are ideal
for transferring abrasive, caustic, particulate laden raw
materials , effluent and highly viscous products.
We offer two types of peristaltic pump designs, one utilizes a
dry roller and the other a lubricated shoe.
series dry roller design only requires a light grease for hose
lubrication. This design is well suited for applications
requiring < 100 PSI and for pure fluids or food related
products due to reduced potential for lubrication related cross
contamination. The 3000 and 4000 series peristaltic pumps have
hose chambers partially filled with lubrication fluid and are
capable of operating at higher pressures compared to the 2000
The pump casing for the dry roller design is less complicated
and therefore less costly than the lubricated shoe design,
however the added lubricity of the lubricated shoe design
enables using a less complex (reduced cost) peristaltic pump
hose. Thus the determination of which design is "best" really
depends upon the characteristics of your specific application.
Generally speaking intermittent duty applications for pressures
< 100 PSI, as well as food/beverage related applications, lend
themselves to the 2000 series dry roller design. Continuous duty
applications and applications requiring pressures > 100 PSI will
be better candidates for the 4000 series lubricated shoe design.

peristaltic pump and hose design
Regardless of the
hose compression design, the five main advantages of industrial
peristaltic pumps include:
- There are no seals to wear out,
inventory or replace. Only the hose is in contact with
the fluid pumped, so with a compatible hose material and
proactive hose replacement reliability is fantastic and
maintenance costs minimal.
- They have great suction lift
capabilities, which is beneficial for many transfer
applications where fluids or slurries are transferred from a
tote, tanker or holding tank to a process or some other
- Peristaltic pumps tolerate
relatively large solids, minimizing filtration requirements.
This also makes them ideal for transferring reclaimed
fluids; a big application for peristaltic pumps is dockside
transfer of raw sewage to temporary storage tanks.
- Peristaltic pumps can be operated
dry as they are not dependent upon the fluid being pumped
for cooling or lubrication. This simplifies a fluid
system by eliminating low liquid level sensing equipment in
some circumstances and reduces product waste for transfer
- Compared to air operated diaphragm
pumps, peristaltic pumps do not require compressed air, will
not stall when run at low RPM's and operate equally well in
both hot and cold weather.
