DESCRIPTION

A submersible pump (or sub pump, electric submersible pump (ESP) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between pump and the fluid surface. Submersible pumps push fluid to the surface as opposed to jet pumps having to pull fluids. Submersibles are more efficient than jet pumps.

Submersible pumps are found in many applications. Single stage pumps are used for drainage, sewage pumping, general industrial pumping and slurry pumping. They are also popular with pond filters. Multiple stage submersible pumps are typically lowered down a borehole and most typically used for residential, commercial, municipal and industrial water extraction (abstraction), water wells and in oil wells.

Other uses for submersible pumps include sewage treatment plants, seawater handling, fire fighting (since it is flame retardant cable), water well and deep well drilling, offshore drilling rigs, artificial lifts, mine dewatering, and irrigation systems.

 

TECHNICAL

Lowara DOC Pumps

Submersible pumps for drainage, infiltration water and emptying of pools, ponds, tanks and reservoirs. The DOC pump is mainly made of stainless steel and the motor has thermal overload protection which makes the DOC versatile, corrosion-resistant and compact. The single phase version has built in capacitor, level regulation and cable with a plug which enables fully automatic operation.

A shallow suction device is available enabling an almost complete drainage of flooded floors (down to 3 mm).

Three basic versions are available:
DOC with open impeller
DOC VX with vortex impeller giving 20 mm free passage for dirty water with solids
DOC GW with non-clogging magnetic float switch system for confined spaces

ABS Robusta Pumps

For the smaller pumping challenges
The Robusta 200 and 300 models are plug-in, submersible pumps designed to remove wastewater containing solids up to 10mm. The pump and motor form a pressure-tight encapsulated fully flood-proof unit . 230v & 110V available.
