Gear Pumps
Gear Pumps
Pulsefree Pumping
Gear pumps allow differential pressures up to maximum 5.6 bar (81 psi)
Low Operation Costs
Interchangeable, magnetically coupled pumpheads
Maintenance-free drives
Only few wearing parts (gears, seals)
Service kits allow the user to exchange worn parts
High quality and precision for an optimum performance even after
many years of intensive use
ISMATEC
®
gear pumps run only
in the clockwise direction
(Exception REGLO-Z Digital).
TheMagneticallyCoupledDrivePrinciple
Consists of two magnets, a
driving magnet that attaches
to themotor shaft and a driven
magnet that is completely
sealed within the pumphead
and is connected to the driving
gear. The driven magnet is a
non-wetted component and is
totally encapsulated.
The two magnets couple
automatically such that the driving magnet turns the driven magnet
and gears without physical contact.
Decoupling occurs when the pump load exceeds the coupling torque
between the two magnets. This feature can act as a safety device to
prevent damage to the pump and motor as well as associated piping.
The magnets can be recoupled by bringing the motor to a complete
stop, eliminating the cause of the decoupling and restarting.

Max. suction height
with water and
fooded pumphead:
8 m, depending on
pumphead
and tubing
Pumping out of a
vacuum of 200 mbar
Based on the traditional gear pump technology
For application with moderate differential pressure
In comparison to the Suction Shoe pumpheads, the Cavity style
pumpheads can be used for viscous media and applications with a
certain suction height
.

product featuring a
patented technology
Modifed pump
chamber compared to
the conventional gear
pump technique
This type of pumphead design
has a seal plate mounted
with a deliberate play in the
suction part of the pump chamber (hence the expression Suction
Shoe). Discharge pressure keeps the Suction Shoe seated tightly on
top of the gears which prevents flow from decreasing in high-
pressure applications.
