Hose compression force adjustment
(shimming)
In order to achieve optimal life of the pump hose, the
compression force of the pump hose can be adjusted by
placing a number of shims under the pressing shoes.
The shims (A) are fitted between the rotor (B) and the
pressing shoe (C). The number of shims will vary for
each discharge pressure situation.
The paragraph
8.8
describes how to select and install
the shims.
4.4.3
Lubrication and cooling
The pump head, in which the rotor and pump hose can
be found, is filled with Bredel Genuine Hose Lubricant.
This lubricant lubricates the movement between the
hose and the pressing shoes and dissipates the
generated heat via the pump housing and the cover.
The lubricant is food grade. See §
11.1.4
for the
required quantity and NSF registration.

Gearbox
4.5.1
General
The hose pump types described in this manual use a
bevel-helical gearbox. The gearbox is mainly used for
high reduction ratios and low input speeds. This
modular construction enables a wide range of
reductions, torques and connection possibilities for the
electric motor.
