Uni-Seal™ Pump & Kits

Brand: Sealweld
Replacement parts for the Uni-Seal Pump are available from CR Wall. To determine which parts you require, please reference the parts document available for download here. Simply send us your required part numbers by completing the "Request Information" form.
The Uni-Seal™ pump has an air/hydraulic motor that can be powered by compressed air, bottled air or natural gas. Up to 10,000 PSI is quickly generated by stepping on the foot pedal making this pump ideal for servicing large diameter valves. The high speed action of the Uni-Seal™ pump makes it ideal for "popping" the plug out of its seat in tapered plug valves that become hard-to-turn.

* Consult your company's safety policy BEFORE operating with natural gas. May void warranty.
