GENERAL INFORMATION
Oberdorfer’s PPS pumps feature injection molded reinforced
polyphenelene sulfide (PPS) plastic housing. This pump has become a
popular cost-effective alternative to metal pumps in chemical pump
applications. PPS is an engineered reinforced plastic offering a wide
range of chemical compatibility, physical stability and high temperature
resistance (to 180o F). Glass fibers are also combined to add strength
and stability. Housing have special designed ribbing and heavy wall
sections. Oberdorfer’s building block design permits ease of servicing
and parts replacement.
Quiet running gears are efficient, use less power, and give a
longer service life. Injection molded PPS plastic supplies close tolerances and stability. Compound additives include glass for strength and
Teflon(R)* for lubricity.
Housings
Gears
Bearings
The PPS pump line was designed with special inert carbon bearings.
These bearings are used for maximum chemical compatibility and also serve
as thrust flanges and wear plates.
Seal options include packing type or mechanical seals made of ceramic, carbon, Viton(R)* or Teflon(R)*. Grafoil rings, Teflon(R)* lip seal. Shafts are
316 stainless steel or high nickel alloy C. The Teflon(R)* o-rings for positive
sealing, independent of internal pump clearances. Also available with close
coupled adapter.

PPS PUMPS
205 SERIES
207 SERIES
Note: Dotten lines (---) recommended for intermittent duty only
due to accelerated wear at higher speeds & pressures.
DIMENSIONS
214 SERIES
* Also available in 1/2” NPT for all pumps and 3/4” NPT for 214 series
Also available with close coupled adapter for NEMA motor frames.
NOTE: Dimensions are not to be used for construction purposes.
The recommended drive arrangement is direct drive between pump and motor using
a flexible coupling (in-line drive). If a pulley drive is required, a separate pillow block
bearing is necessary to absorb the belt tension. consult factory for applications
beyond the above specifications or for product options not shown.
AN INTERESTING APPLICATION
One of our more inventive distributors asked us to design a PPS pump with at least 13 GPM
capacity. He uses these pumps to pump a very cold liquid that is used to keep fish fresh as part of
an onboard commercial fishing vessel system. Originally the distributor used one motor and one
speed control to drive two of our pumps. The pump closest to the motor had a through drive shaft.
One end of the drive shaft was coupled to the motor and the other end was coupled to the second
pump. Pictured to the left, is the tandem PPS pump that we at Oberdorfer Pumps designed to
replace the two pumps. This saves money, space, and provides for a very flexible system. Come
to us with your unique needs. We’ll work with you.
