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 counterpressure situation.
describes how to select and install
the shims.
4.4.3
Lubrication and cooling
The pumphead, 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 §
for the
required quantity and NSF registration.
4.5
Gearbox
The hose pump types described in this manual use
planetary gearbox units. The gearbox units are
characterized by their compact and modular
construction.
This modular construction enables a wide range of
reductions, torques and connection possibilities for the
electric motor.
Consult your Bredel representative for
lubrication recommendations when operat-
ing the hose pump below 2 rpm.
