high discharge pressure Compare with Spool switch, drive air loss is less than 1/10 at dead-headed or standby. Wider operation pressure range Variable flow rates The pumps will run anywhere within their operating range by simply adjusting the liquid discharge settings. •Note: When there is possibility that liquid expands by temperature change in the pipe and increass of inner pressure of pipe, safety valve must be installed. Self priming Design of pumps allow for good suction lift even with fluids contain air. Maximum suction lift is 5.5m. The pumps can run dry without damage. 'Note: Do not...

New mechanical switch allows stable stroke even with the unstable air supply. The pumps can operate with low pressure air. It is effective to transfer shear sensitive material. High discharge Maximum discharge pressure is 0.85MPa (metal casing model). Minimized inner loss maximizes actual use discharge pressure Discharge pressure can be adjusted easily filter press general industry, chemical industry, viscosity liquid The pumps can handle most chemicals including highly corrosive fluids like acids. Also, high viscosity fluids and fluids containing solids can be transferred. Maximum...

With built-in anti-explosion specifications, this device is for the transfer and circulation of liquids at such places as general industries, chemical manufacturers, and ceramics plants. This product is optimal for such machinery as filter presses. Specifications:Pump size, 1-1/2 (40A); Maximum liquid discharge, approximately 370 L/min; operating noise, 98 dB.
