Our Drive Plates Pumps & Drive Plates

Our Micro90 series drive plate is a precision 7
engineered die cast aluminium construction,
specifically designed to be compact, lightweight
and versatile.

It caters for multiple options of integral
mechanical or solenoid operated control valves
as well as providing an interface for custom
designed control valve manifold assemblies. It
also incorporates steel seated inserts for both
pressure line check and relief valve. Furthermore,
the drive plate has an option for pressure
compensated flow control valves (in lift, hold and
lower configuration) as well as various porting
facilities and mounting options. The drive plate
also accommodates our comprehensive range
of Group 0 gear pumps and DC electric motors
allowing for the best balance of power, output
and efficiency.

Our Pumps

Our Micro90 series range of Group 0 gear pumps
cover several different displacements varying
from 0.26 cc/rev up to 1.0 cc/rev.

Key features include:

>>compact design

>>high mechanical and volumetric efficiency

>>low noise

Nominal working pressures are 180 bar to 210
bar with maximum peak pressures ranging from
180 bar to 240 bar. All pumps are clockwise (CW)
rotation and are protected by an integrated high
efficiency suction filter element within the power
unit build.

See ordering code section on page 14 for
available displacements.
