Close-Coupled External Gear Pumps
Refer to form L-4082 for General Operating and Safety Instructions.
Description
Shertech self-priming, positive displacement, external rotary gear pumps are ideal for a wide range of intermittent and
light-duty industrial, marine, agricultural, and commercial applications, providing a nearly pulseless flow. Close-coupled
models are available directly mounted to NEMA framed, AC ODP single-phase, thermally overload-protected motors or as
pump heads only for custom installations. All models include a pressure relief valve. Motor-driven models are HP configured to
handle up to 500 SSU at 100 psi (specific gravity of 1.0).
Uses: For use with non-particulate and non-abrasive fluids compatible with pump wet-end construction component materials.
• Flows to 4.4 GPM.
• Max. RPM: 1725.
• Max. PSI: 100.
• Maximum viscosity of 500 SSU at 1725 RPM (max. input torque of 45 in.-lbs.).
• Pumps can operate bi-directionally (reversible). In reverse operation, the pressure relief valve will not function.
• Temperature ranges from -20° to 210° F.
• Maximum working pressure: 150 PSI.
CARBONATOR-MOUNT CAST IRON PUMPS (INTERMITTENT DUTY) – Specifically designed for use with oil-based fluids. Not
to be used with water-based fluids. Pumps include steel spur gears with steel shafts and cast iron shaft support; standard
pressure relief valves that can be ported internally or externally and a Viton mechanical carbon/ceramic-faced seal with
temperature range of 32° to 280° F. Wet-end parts are constructed from cast iron, steel, stainless steel (302, 303 and/or 18-8),
carbon, ceramic, and Viton.
CARBONATOR-MOUNT BRONZE PUMPS (INTERMITTENT DUTY) – Excellent for water-based fluids. Feature 303 stainless steel
shafts, carbon graphite bushings, and Buna-N mechanical carbon/ceramic faced seal with a temperature range of -20° to 210° F.
Standard pressure relief valves can be ported internally or externally. Wet-end parts are constructed from bronze, brass,
stainless steel (302, 303 and/or 18-8), graphite, carbon, and Buna-N.
PUMP HEADS (NO MOTOR) – Close-coupled gear pump heads are designed to direct couple to carbonator pump motors
(See NEMA Spec. MGI-18.739, Dimensions of Carbonator Motor mounting). The face of this gear pump has been machined to
match the carbonator motor face. Pump and motor held together with a stainless steel beveled "V" band clamp. Coupling of
shafts is done by mating the carbonator motor's slot with the pump's slot using the Oldham coupling (See Figure 2). This positive
displacement characteristic offers a wide range of applications.
NOTE: See Rotary Gear Pump Selection Guide in the Motor Manual for suggestions concerning installation, selection, options,
and accessories.
WARNING: Do not use to pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc. Do not use in flammable
and/or explosive atmospheres. When pumping hazardous or dangerous materials, use only in room or area designated for that
purpose. For your protection, always wear proper clothing, eye protection, etc. in case of any malfunction. For proper handling techniques
and cautions, contact your chemical supplier, insurance company and local agencies (fire dept., etc.). Failure to comply with this warning
could result in personal injury and/or property damage.
