Self-priming pumps
LOWARA SHE-SHS-SHF
2-POLE
Description
Specifications
The SH serie from Lowara is normal priming, but
thanks to a special technique developed by Van der
Ende Groep, it is possible to make this serie of pumps
self-priming. The SH serie self-priming pumps can be
used in industrial and horticultural applications. The
hydraulic part of the pump is made of AISI 316 and the
self-priming tubing is made of pvc (16 bar). The pump
is standard available with a 3-phase motor.

SHE pumps in self-priming version
In some cases, it is necessary to make use of a selfpriming pump. The SHE serie from Lowara is normal
priming, but thanks to a special technique developed
by Van der Ende Groep, it is possible to make this
serie of pumps self-priming. We have been doing
this for almost 20 years. Thanks to this customisation,
it is now possible to continue deploying system pumps
from the SHE serie, which are used for their large
capacity and lifts.
The technique used has been carefully reviewed and
modified. Now a valve is used which shuts off the
bypass once the pump is pumping water.
This makes a difference to the loss of pressure
and capacity or, in other words, the yield.
The suction opening is constructed with a 45° Y-piece
so that the suction pipe can be installed above the
pump house at an angle of 45°, so that a water seal
is created.
The valve is available in both a manual and an automatic version. In the automatic version, the bypass
is closed once the water has been sucked up and the
pressure built up.
