Graco EP Series

Peristaltic Hose Pump Technology

Single, oversized roller compresses a low friction hose through
a full 360-degrees of rotation

• More flow per revolution than conventional designs

• Inexpensive to maintain – no valves, seals or glands

• Pumps are reversible and can be used to empty lines or clear blockages

• Integral drive and motor can run as low as 1 rpm

• Extended hose life - only one hose compression per revolution

EP SERIES HOSE PUMPS

• One hose compression per
revolution extends hose life

• Quick replacement of hose
and tube

• No moving parts in the
fluid stream

• One-piece “quick change”
assembly for easy service

• Pump speeds as low
as 1 rpm

• Easier access to
internal parts, making
maintenance fast
and simple

Unique Advantages

Graco’s positive displacement
hose pumps rotate a full 360-degrees.

Because they use a single roller to compress the hose

once per revolution, your hoses last longer so you have

less maintenance and downtime.

EP Series PumpsBuilt to Handle

Only the interior of the hose is in contact with the fluid being

pumped, making it easy to sterilize and clean the inside pumping

surfaces. The gentle pumping action is ideal for shear sensitive

materials and fragile cell cultures.

Innovative hose design

Graco’s 360-degree hose pump is designed to put 40% less

stress on the hose

running at the same flow rate. The hoses are highly engineered for

long life and durability and are available in a wide variety of

configurations for the most demanding applications and materials.
