Material

The turning of the helical shaped rotor within the stationary stator
creates a progressing cavity similar to a moving piston. Liquid is thus
displaced generating a pumping action.
Unlike piston pumping, extremely high pressure cannot be created because the stator is made of Buna N and is flexible. Because of
this flexibility contaminated liquids can be handled.
Close fit of the rotor within the stator permits lifting of liquid on the
suction side as high as 20 ft. High starting torque motors are recommended in order to overcome the high starting friction of the stator.
The pump is relatively quiet.

ROTATION
Bronze
This helical rotor design demands a single rotation - clockwise
when facing the pump drive shaft. Pump rotation and “in” and “out”
ports are indicated on the dimension diagrams on reverse side.

MATERIALS OF CONSTRUCTION
GASOLINE ENGINE MOUNTING
These pump housings and mounting brackets are made from cast
aluminum or bronze alloy. The rotor is made from stainless steel with
a hard chrome plate for improved wear properties. The stator is made
from molded Buna N. The mechanical seal is a carbon and ceramic
rotary face type for positive sealing.
This pump is supplied close coupled to gasoline engine or
as a pump alone complete with attaching parts and instructions
for mounting. Any 2 or 4 cycle gasoline engine having a standard
S.A.E. 4 bolt mounting flange and 5/8 inch shaft diameter with
keyslot can be used. An engine rating of at least 2.2 horsepower
at 3600 R.P.M. is necessary as only about one-half of rated
power is available at the recommended pump speed of 2100
R.P.M. Larger horsepower engines (3 H.P. at 3600 R.P.M.) with
5/8 inch shaft diameter and suitable flange mounting provide
extra power to compensate for power losses due to carbon
deposits and gumming.
LIQUIDS
The corrosion resistant alloys used are compatible with common
liquids including water, water solutions, oils and many commercial
chemicals. Severe solvents are not compatible with the Buna and
should not be pumped.
