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is withdrawn.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).
Description (continued)
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.
Inspect the magnet cup, hub, or adaptor (if present) before assembly
with the motor. Replace or repair if there are signs of damage.
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.
