Dual Solenoid Variable-speed Liquid and Gas Piston Pumps

Dual Solenoid Variable-speed Liquid and Gas Piston Pumps

  • Ideal for liquid and vapor refrigerant recovery, water sampling/treatment, and volatile chemicals

  • Oil-free and leak-proof
  • Only one moving part and two check valves
  • Compact and quiet (<60 db for liquids)

With the variable speed rate controller, pumps feature multiple control options for adjusting the flow of your fluid or gas. Control options include: manual on/off switch, dry contacts (for remote on/off), 4 to 20 mA (with 79306-75), and PC or PLC interface. Custom control options are available, call our Application Specialists for availability.
Pumps also include integral overload protection, run-dry capability, self-priming up to 22-ft, an integral solid state circuit board (for control of pump cycle rates) and submersible connections.
Alternately energized and de-energized coils located at either end of the pump change the magnetic field surrounding the piston. This results in movement of the piston back and forth within the piston cylinder and hence movement of the fluid. The check valves located in the piston and pump outlet prevent any reverse flow from occurring.
Required system components include: a variable-speed liquid or gas piston pump, a variable-speed rate controller (with or without a 4 to 20 mA input), a signal power cord, and a power cord.
Note: Call our Application Specialists for longer signal and power cord lengths.
