Series 3000 液压膜片泵

Hydraulically Actuated Diaphragm




The AQUFLOW® Series 3000 is a rugged, compact, hydraulically actuated diaphragm metering pump. The pump is available in simplex or duplex configuration, with independent capacity adjustment for each pumphead.

All drive parts are fully enclosed and operate in an oil bath which minimizes friction and wear while providing protection from harsh environments. A self-compensating hydraulic system assures diaphragm position and eliminates the need for troublesome vacuum breakers and refill valve.

The easy to read micrometer knob enables convenient capacity adjustment between 0-100% while the pump is operating or stopped. In addition to manual control, the pump can be supplied with optional automatic capacity control, making it possible for the pump to control the flow rate in proportion to various process signals. A simple, externally adjustable, internal hydraulic relief valve protects the pump and the process from pump induced overpressure situations.

Features:
• Design Capacities of 15.9 to 482 GPH
• Discharge Pressures to 675 PSIG
• Metering Accuracy of ±1%
• 10:1 Turndown via Stroke Length
• Internal Hydraulic Relief Valve
• Modular Design With Multiple Options
• Specifically Matched Accessories
