Description
Cavity Style Gear Pumps - Series GAT, GD, GJ, GK, GL, GM, GN
Cavity-style gear pumps are rotating positive displacement pumps. The main pump
components are fabricated of a variety of machined metal components, the gears and
bushings are molded or machined from plastics, and a variety of perfluoromers and
elastomers are used for the static seals. There are no dynamic seals. These pumps
are magnetically coupled to their drive. The driven magnet is fixed to the driving gear
shaft . Rotation of the hub magnet by the drive causes the driven magnet and driving
gear to rotate synchronously. The magnet cup provides a pressure boundary between
the pumped fluid and the surrounding environment. Fluid enters the inlet port and is
swept by the gears around the cavity to the outlet port. Pressure is developed in the
pump by restrictions on the outlet, which load the gears against the cavity and the
shafts against the bushings. In most cases, the pumped fluid provides the cooling
and lubrication for the bushings. Some pumps are fitted with an internal bypass. By
setting the spring tension in the bypass assembly, the discharge pressure can raise the
bypass poppet recirculating fluid to the inlet side of the pump. Pumps without bypasses
can be operated in reverse direction with degradation in performance and reduction in
life. Contact your local Micropump distributor or contact Micropump directly for pumps
designed to operated continuously in reverse direction.
Suction Shoe Gear Pumps - Series GA, GAH, GAP, GB, GC
Suction shoe gear pumps are rotating positive displacement pumps. The main pump
components are fabricated of a variety of machined metal components, the gears and
suction shoes are molded or machined from plastics, and a variety of perfluoromers and
elastomers are used for the static seals. There are no dynamic seals. These pumps
are magnetically coupled to their drive. The driven magnet is fixed to the driving gear.
Rotation of the hub magnet by the drive causes the driven magnet and driving gear to
rotate synchronously around a non-rotating shaft. The magnet cup provides a pressure
boundary between the pumped fluid and the surrounding environment. Fluid enters
the inlet port and is swept by the gears around the cavity to the outlet port. Pressure is
developed in the pump by restrictions on the outlet, which load the gears against the
suction shoe and shafts. In most cases, the pumped fluid provides the cooling and
lubrication for the bearing area. Initial start up of the pump is facilitated by a spring
or ball that holds the suction shoe in place until differential pressure across the shoe
dominates the load on the shoe. Some pumps are fitted with an internal bypass. By
setting the spring tension in the bypass assembly, the discharge pressure can raise the
bypass poppet recirculating fluid to the inlet side of the pump.
Centrifugal Pump – Series CA
The Series CA are centrifugal pumps fabricated of 316 Stainless Steel or Hastelloy C.
Bearings are Teflon, PPS or PEEK. Static seals are Teflon or Viton.
Centrifugal pumps are rotating, dynamic pumps. The pump is magnetically coupled
to its driver. The driven magnet is fixed to the impeller. Rotation of the hub magnet
by the drive causes the driven magnet and impeller to rotate synchronously around a
non-rotating shaft. Fluid enters the axially located inlet port and is accelerated by the
impeller to the tangentially located outlet port.
Pressure is developed in the pump by restrictions on the outlet, which causes the
impeller to load against the thrust plate. The magnet cup, formed from 316 SS
or Hastelloy C, provides a pressure boundary between the pumped fluid and the
surrounding environment.

Unpacking and Storage
If you have purchased a pump/motor combination this will be assembled ready
for installation. If you have purchased a pump without a motor you may require a
Micropump, NEMA, or IEC/ISO adaptor. If you have purchased an adaptor ensure you
have suitable pump or motor for your system. Contact your local Micropump distributor
or contact Micropump directly for assistance in selecting compatible components.
Use of non-Micropump adaptors may adversely affect your product
performance, installation category, and warranty. Contact your local
Micropump distributor or contact Micropump directly for information.
Motor Adaptors
Mounting screws are provided with Micropump supplied motors and adaptors.
Mounting screws are not provided with pumps or adapters.
NOTE
CAUTION
Piston Pumps - Series PD, PF
The Series PD and PF pumps are reciprocating piston pumps. The Series PD pumps
use a pair of pistons and a rotating valve to positively displace fluid. The Series PF
uses a single reciprocating and rotating piston without valves to positively displace
fluid. The main pump components are fabricated from a variety of machined metal
and ceramic pistons, molded and machined plastics and elastomer seals. Piston
seals are dynamic and other seals are static. Pumps are directly coupled to drive
units. The series PD drive rotates a swash plate that axially displaces the pistons. The
series PF drive rotates an angled piston, generating a combined axial and rotational
displacement. With the outlet port closed, fluid enters the inlet port as the piston
is withdrawn. With the inlet port closed, fluid exits the outlet port as the piston is
extended. Pressure is developed by restrictions in the outlet, causing the pistons to
load against the swash plate (Series PD) or the drive shaft and pump body (Series PF).

Inspect the magnet cup, hub, or adaptor (if present) before assembly
with the motor. Replace or repair if there are signs of damage.
Before installing the product ensure all transit packaging has been removed.
Remove the blanks from the pump inlet and outlet ports. If the pump is to be stored
prior to installation, re-pack the pump in its original packing, refit the blanks to the ports
and store in a dry, covered environment.
Protect the pump head, hub, or adaptor from damage during unpacking and installation.
Impacts to the magnet cup can cause internal damage or result in rub between the
magnet cup and driving magnet upon assembly with the motor. Damage to the hub or
adaptor may result in rub between the magnet cup and driving magnet upon assembly
with the motor.
DOC No: 7046 REV G

The foundation must be capable of supporting the combined weight of
the pump and motor and provide a rigid support.
If the pump head housing assembly and motor are supplied separately they will need
to be assembled prior to the installation. Align the housing flange so that it fits into the
matching recessed flange on the motor assembly and tighten screws evenly. Align the
pump head components with the housing flange and secure with the supplied screws.
Tighten screws evenly and in an alternating pattern. Refer to the service instruction
sheet for the specific pump model being used for proper torque values.
Assembly
Proper assembly is required to prevent magnet rub due to misalignment.
Loose pump head or adaptor bolts may cause misalignment which
may result in magnet hub rub on the magnet cup causing high surface
temperatures or weakening the pressure boundary created by the
magnet cup.
Space Requirements
Refer to the Technical Specification for overall dimensions and weights of the pumps
covered by this guide.
Location
Pumphead or adaptor cannot support the weight of the motor. Ensure
the motor is adequately supported by the foundation and/or mounting
bracket.
The pump should be located with the inlet below or even with the liquid level of the
fluid supply. The pump can be mounted in any position. Ensure that there is adequate
space for operation, inspection and maintenance.
DOC No: 7046 REV G

CAUTION
Filtration
The pump can be damaged if the fluid being pumped has abrasive
suspended solids. Always install a suitable filter or strainer when these
fluids are being pumped.
All strainers and filters should have large surface areas to prevent excessive
pressure drop.
For open systems the filter must be installed on the inlet side of the pump. For closed
loop systems the filter can be installed on the inlet or discharge side.
Ensure filters are of the correct size for the pump being installed, refer to the table
below for correct sizing:
