Pump more to your bottom line

Graco offers three vigorously tested models engineered for long-life
and reliability. Each model has patent pending, innovative designs
to perform in best-practice applications for a durable solution that is
hard to beat.

Innovative Double Ball Outlet Check

The improved design geometry eliminates the spring used
on older pump styles to make vapor lock a thing of the past

Armored Sight Glass

Heavy duty cage and shatter-proof glass provide
easy visual indication of oil flow and volume

Dynamic Captured Seal Design

An Improved O-ring design provides a better seal
over old rubber boot or gasket designs to eliminate
leak paths that lead to system contamination and
pump damage

Accessories

Alarm

Shaft rotation low level alarm

Stainless Steel Piston and Spring

High quality stainless steel piston and spring is
corrosion resistant. Components are match fit
to tight tolerances for consistent output with no
by-pass

Superior Roller Bearing

Exclusive ball bearing roller design has superior rotation to help
protect cam lobe from damage–roller bearings don’t stick like
simple roller-on axle design. Larger diameter roller spreads load
pressure evenly to reduce wear and improve pump life

Patent Pending Ball and Socket Design

Patent pending Ball-in-Socket design spreads force evenly
over piston tip to avoid bending and wear for longer piston and
rocker life. Precision stroke length (~.05") eliminates vapor
locks for improved flow and delivery.
