Description
NOTE
Components within the fluid-wetted
path of this pump are stainless steel
and PTFE.
NOTE
This pump is tested in mineral oil.
Flush pump thoroughly with a solvent
compatible with product dispensed as
required.
The major components of pump model
7835-SDTR1 consist of a reciprocating air
motor and a double-acting pump tube.
The pump tube is separated from the motor
in order to:
• protect the motor from product
contamination.
• allowsseparation without product leakage.
The pump tube is designed to enable the
delivery of a variety of materials.
This medium-pressure (5:1) pump includes
a bung adapter, 2 in NPTF (e), that allows
operation directly from original 55 gallon
(200/205 l) drums.
