MODEL
BRONZE OR ALUMINUM
CLOSE COUPLED HELICAL ROTOR PUMP
101
101B
PIPE SIZE 3/4
FEATURES
• All Bronze or Corrosion Resistant Aluminum
Construction
• Easily Mounted in Field to your own 56 Frame
Motor & 56C for explosion-proof motors
• Carbon Face Mechanical Seal
• Quiet Running
• Can Handle Contaminated Liquids
• Buna Stator and Stainless Steel Rotor
CHARACTERISTICS
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
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
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 mechanical rotary face type for
positive sealing.
ELECTRIC MOTOR MOUNTING
This pump is supplied close coupled to electric motor or
as a pump alone complete with attaching parts and instructions for mounting. Any 56 frame electric motor (or 56C frame)
with 5/8 inch shaft diameter, 1725 R.P.M. and of horsepower
rating as listed above can be used. The motor can be rigid or
resilient mounted, sleeve or ball bearings, 50oC rise, capacitor
start, counter-clockwise, rotation from shaft end. (For Gas
Engine version, see models 111-UGY/111B-UGY)
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.
