Description
The 331380 series pumps consist of an air
motor and a double-acting reciprocating
pump tube.
These high-pressure pumps (50:1 ratio)
are designed to deliver a range of light to
heavy lubricants directly from an
original container.
Each pump model is designed with a
pump tube length to accommodate different
size containers (→ Table 2).
Models 331380-MA and -MB are
equipped with air motor 324300-M which
contains BSPP air inlet and BSPT material
outlet adapters (→ Table 3). Additional
accessories are available
(→ Table 4, page 7).
All models have nameplates except
331380-C5, 331380-D5, and 331380-N1.
