The Add-A-Phase® phase converter from Ronk has operated three-phase pump motors from single-phase power sources since 1952. This converter is ideal for automated applications where the motor operates at a constant horsepower load, as most pumps do. The converter’s ability to limit inrush currents and operate at a high power factor make it possible for the power supplier to allow larger horsepower motors on their lines.

Pump grit shield

Sometimes pumps suffer from erosion adjacent to the wear ring, due to grit trapped on the high pressure side of the ring, which becomes an abrasive slurry rotating at half the pump speed, eating away at the fronthead.

The long-life silicon carbide seals used in WILO EMU pumps and mixers have repeatedly demonstrated their ability to last 15 to 20 times longer than ordinary carbon-ceramic seals (and 2-½ to 3 times longer than tungsten carbide materials). This is particularly important because seal failure of any kind usually results in extensive damage to motor windings and motor bearings.
