Oligear Variable Volume, Pressure Compensated Piston Pump

• No wasted horsepower, flow on demand.
• More dirt-tolerant and longer life than gear, vane or competitive piston pumps due to hardened steel running surfaces.
• Can run either water glycol or petroleum-based fluids without sacrificing performance.
• Do not need to reduce motor speed to run with water glycol like many competitors!
• Adjustable low level float switch – Shuts down system in the event of a leak.

Solid manifold with pressure compensated flow controls integral.

(3 for 10 H.P. and 4 for 20 H.P. with room to add 2 more). Fittings included.

• Plug and play! Can run multiple motors with no additional priority flow controls or flow dividers required.
• Manifold is anodized for use with water glycol.
• Customer does not need purchase tees, manifolds, etc., to tie in return oil to filter.
• No wasted horsepower, flow on demand.
• Optional Solinoid shut off valve.
• Return filter with micro-glass element—not paper.
• Can be used with either water, glycol or petroleum-based oil.
• Higher dirt-holding capacity than paper, which results in longer-lasting elements.
• Absolute versus nominal filtration, which results in cleaner fluid.
