Wolverine Variable Speed Pump

Wolverine Variable Speed Pumps

Graco

Features: The variable speed Wolverine pump provides continuous injection for an even dispersion of chemicals. Flow rates are adjusted between 10 and 100% by a control dial on the motor eliminating the need for a localized controller. The fluid heads are interchangeable between all Wolverine Advanced series pumps. High efficiency 12 or 24VDC brushless motors use less amperage draw than traditional brushed DC motors. It can be integrated with the Harrier+ and alternative energy sources for a fully automated, green pump.

Available in simplex or duplex configuration with flow rates from 2 LPD up to 370 LPD (based on configuration), and pressures ranging from 600 PSI to 10,000 PSI.
Class 1, Div 2, Groups A, B, C, D.

Pneumatic Driven Pumps

Python Pneumatically Operated Pump

Features: Python pumps are ideal for applications that require a pump to operate in a potentially explosive atmosphere and can run off regulated natural gas or compressed air. The Python uses half the air consumption of other pumps in the market. Plus, the Python’s extreme duty plungers, seals, and timing valve are designed for years of operation before replacement.

Pythons are offered with Chromex and Ceramic coated plungers and a standard 316 SST fluid section/wetted parts. HNBR, FKM, FKM ETP, TFEP, and FFKM plunger packings and check valve seals available.

Double Acting
• Pumps fluid in both directions of the stroke for increased flows
• Provides continuous flow operation for better pump efficiencies

Self Priming
• Anti-locking so air cannot get trapped inside air motor and stall pump
• Pump can free itself of air and resume pumping without any adjustments

The pump is capable of up to 3000 LPD and pressures up to 6000 PSI.
