S Series Rotary Gear Pump

SPECIFICATIONS

General

Design: Drive speeds to 1800 RPM; discharge pressures to 200 PSI;
     flow rates to 32 GPM; foot or flange mounted; with or without
     integral relief valve.
Material: Cast Iron casings with precision machined, heat treated
     gears and case hardened shafts. Pumps are also available in Ductile Iron,
     316 Stainless Steel and Carbon Steel.
Gears: helical gears
Bearings: Replaceable iron sleeve bearings. Also available with carbon
     graphite or bronze bearings.
Seal: Self adjusting mechanical seal. Also available with compression
     packing or lip seal. Mechanical seal and lip seals available with different
     elastomers for pumping different types of liquids.
Lubrication: Self-lubricating using the pumped liquid. Also available for
     handling non-lubricating liquids.
Rotation: Pumps may be operated in either direction. Discharge is
     always on the side of the pump toward which the top of the shaft
     rotates. Specify when ordering.
Liquid Viscosities: 32 SSU to 100,000 SSU. Adaptable for handling liquids
     from water soluble to molten lead.
Suction Lift: Up to 28" Hg / 31 feet depending on the type of liquid
     being pumped.
Drive Options: E-Drive (pump close coupled to motor); A-Drive (pump
     connected to C-face motor with adapter bracket and coupling);
     D-Drive (pump coupled to motor mounted on base plate); GR-Drive
     (pump coupled to gear reducer coupled to motor mounted on base plate);
     B-Drive (pump and motor connected by V-belt and pulleys mounted on
     base plate).
Accessories: Repair Kits, Gear Sets, Bearing Kits, and Seal Kits.
FEATURES

PRECISION GROUND JOINTS
     No Gaskets - Perhaps the biggest advantage to these pumps. As gaskets
     are not used, original tolerances are maintained for consistent performance 
     and the time once lost in halting operations to replace a worn gasket
     is saved.
BEARINGS
     The heart of the pump. Sleeve and plain bearings are especially adapted to 
     maintain even gear and shaft rotation for normal pump service. Anti-friction 
     bearings minimize friction and provide higher load ratings for medium to high 
     pressure service. Anti-friction and sleeve type bearings are replaceable.
SEALS
     Self-adjusting mechanical seal provides an ample safeguard against
     liquid leakage and the entrance of air.

PRINCIPLE OF OPERATION

Note: Unit is dimensioned with optional integral relief valve (F dimension). The purpose of the relief valve is to relieve pressure in the pump when the discharge line is closed or otherwise obstructed. This is accomplished internally by routing the discharge back to the suction side of the pump when discharge pressure exceeds the set value. The relief valve is designed as a safety device and is not intended as a directional control valve nor is it intended for use under conditions calling for extended periods of by-pass. The relief valve should always be positioned on the discharge side of the pump. Placement on the suction side of the pump will render the pump inoperable.

S-Series pumps are available as base mounted pump and motor assemblies. Each assembly includes the base, flexible coupling, coupling guard, riser blocks (if required),lifting eye-bolts, and mounting hardware. The fabricated steel or channel steel bases are available with optional features such as drip-lip construction, drain plugs, mounting lugs, casters, etc..
