The NIKKISO Hydroflo® Series 1000 with auto degassing liquid end is a rugged, compact, hydraulically actuated diaphragm metering pump specifically designed to precisely meter process fluids which tend to off-gas easily.
With its unique self-venting head, the pump continually removes undissolved gases from difficult to handle fluids such as sodium hypochlorite, hydrogen peroxide, hydrazine, ammonia, etc. -- resulting in accurate, pure liquid metering. The high suction lift feature enables the pump to operate in applications with low NPSHa. It is available in either 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.
