Medium-Pressure Stainless Pump
Description
NOTE: The components within the fluid-wetted path of
this pump are stainless steel and Teflon.
This pump is tested in mineral oil. Flush the pump thor-
oughly with a solvent compatible with the product dis-
pensed 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 divorced from the motor which:
• protects the motor from product contamination
• allows separation 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 " NPTF (m)] that allows operation directly from original 55-gallon
(200/205 l) drums
