Sand resistant materials and design
Groundwater often contains abrasives, such as sand, that sooner
or later-will wear out both
pump and motor. In order to minimize wear and to provide maximum
lifetime and optimum
performance, the SP range is designed to let the suspended
particles be flushed out of the
pump with the pumped liquid. Both the chambers and the impellers
of the SP range are
made of high-grade stainless steel.

As standard, all HMA Grundfos SP models are made entirely of
stainless steel DIN w-Nr
(AISI304). Where particularly aggressive liquids are
encountered, the SP pumps are available
in extra high grade stainless steel DIN W- Nr. 1.4401 (AISI
316), or, for server conditions,
DIN W Nr. 1.4539 (AISI 904 L).
Erosion and corrosion of a pump mean loss of material and,
consequently, a drop in
performance and efficiency of the pump. In terms of cost of
Ownership, high efficiency of abrand new pump is useless if the
efficiency starts to drop the moment the pump is brought
into operation. Therefore, HMA Grundfos SP pumps are made
entirely of high grade
stainless steel. This material ensures high efficiency and low
energy costs during the entire
life time of a pump.
The highly efficient submersible motors used with the HMA-
Grundfos SP pumps, are rated
among the very best in two basic versions in a variety of sizes
from 4 to 12.submersible
motors are 2-pole asynchronous squirrel-cage canned motors with
thrust journal bearings.
The motors are made entirely of stainless steel, standard
version to DIN W-Nr 14539.
