Reliability
- Self-compensating hydraulic system – no refill valves or vacuum breaker to adjust.
- Single guided ball check valves assure pumping accuracy at low flow rates.
- Precision plunger/bore fit eliminates packing and extends service life.
- Internal hydraulic relief valve protects the pump and discharge line from system over-pressure.
- No plunger packings to leak or require adjustment.
Durability
- Hydraulically actuated leak proof PTFE diaphragm acts as a separating membrane between hydraulic and process fluids – diaphragm is subjected to uniform gentle stresses for maximum life.
- All moving parts operate in an oil bath, greatly reducing friction wear and assuring long, efficient pump life.
- Industrial duty material and coatings.
- Plastic control knob with stainless steel collar for easy adjustment and corrosion resistance.
Compatibility & Flexibility
- Wetted parts are available in a variety of materials to suit the application.
- Flanged housing accepts standard 56C frame motor and acts as an oil seal to keep oil in the housing.
- Available in simplex or duplex configurations.
- High viscosity liquid ends are available.
- 3/4″ FNPT inlet on suction check valve.
- Right angle check valves allow for easy installation and less stress on the suction and injection line fittings.
- Check valves can be removed for low cost maintenance.
- Compact design fits in tight areas.
