 Catalog and dimensions

The maximum delivery rate depending on the delivery head.
Note that the optional single-phase variant has about 10% less power in each case.

The housing is made of extruded aluminum or non-flammable, acid-resistant plastic in accordance with the following standards: VDE 0730 and UL 94. The pump shaft is made of V-2A steel, the bearings are from NSK, extremely durable and vibration-damped in semi-rigid shells mounted, which leads to an almost vibration-free run.

They are used for pumping cooling water, cooling emulsions as well as low-viscosity drilling and cutting oils in all cutting machine tools. They are known in the industry as reliable pumps and have been used with good success for years. Submersible coolant pumps work as centrifugal pumps, with the stuffing boxes and suction line being dispensed with due to the pump part protruding into the liquid. They are largely insensitive to contaminated coolants.

When commissioning, pay attention to the direction of rotation (see arrow on the housing). The liquid level should not exceed a few cm below the flange and minimally cover the pump. The pressure line to the workpiece should be 1/2 inch if possible so that the values ??given in the table are achieved. Any lower amount can be set using a stopcock. Pressure relief valves are not required. The submersible coolant pumps are not designed for dry running.
