WOB-L Piston Pumps

WOB-L piston pumps work to reduce a volume by a fixed crank-driven piston within a cylinder.

Features & Benefits

Compact, reciprocating design for vacuum or pressure
Oil-less, non-lube piston and cylinder
Lightweight die-cast aluminum components or highly wear-resistant plastic
Single stage and multistage models
Balanced for low vibration operation
All wetted aluminum parts treated for corrosion protection from moisture
Long-life, high performance piston seal
Permanently lubricated bearings
Flow rates up to 7.1 cfm (200 l/min), pressure to 160 psi (11 bar), vacuum down to 29.1 in.Hg (-990 mbar)
