Simplicity and economical operation in the pumping plant characterize
the pf series submersible swage pumps whose large passage cross-section
of the impeller also minimizes the clogging hazard these pumps can be
installed in underground pits, with complete reliability, a minimum of
maintenance and no harmful environmental effect. Quick coupling and
uncoupling with guides, from outside the well, allows this series
equipment to be used for west waters, swage, untreated fiber and
solid-laden industrial effluents, air and gas caring liquids ,raw sewage
and active sludge.
The versatility of
non-clog, large free way, single or multiple-vane and vortex impellers
makes it possible to choose the right version form each application, a
meticulous impeller design and engineering with cad-cam techniques
yields high rates of efficiency . Besides, there are different
constructional material for the pump body and impeller according it the
abrasiveness and corrosiveness of the fluid to be handled.
Cooling of the internally dry,
air-filled motor is by means of the pumped liquid that circulates
through the motor jacket. To isolate the dry motor from the pump, a
sealing system comprised of a double mechanical seal with oil chamber.
Is provided. The shaft , common to pump
and motor ,is mounted on grease-lubricated ,low maintenance
bearings .these pumping sets can be installed inside the well ,
they can work partly or totally submerged . In this, they slide
vertically along rails and coupling takes place automatically
through their own weight.
Such groups are intended for operation
in urban waste water collector, sludge and silt treatment plants,
backwater processing installations in paper mills, sugar refineries,
steel mills, chemical and food industries, and generally in all sorts of
sewerage systems.
