Heavy Duty S Series Rotary Gear Pump

Clark Solutions
Heavy Duty S Series Rotary Gear Pump
Pressure to 300 PSI, Flow to 175 GPM, Drive Speed to 1800 RPM

DESCRIPTION
Heavy Duty S Series pumps are capable of higher pressures and flow rates than the standard S-Series.

The pumps are available in cast iron (standard) and ductile iron. They are designed to operate at speeds to 1140 RPM, pressures to 300 PSI, and flow rates to 175 GPM. The standard seal is a mechanical self adjusting seal with Buna-N elastomer. Lubrication of the anti-friction bearings is accomplished by the circulation of the pumped liquid. All models are available with foot mounting.

These pumps are self-priming and unidirectional. The machining of the gears, shafts and housing faces are held to exacting tolerances (within 0.0005") resulting in a pump with better lift, reduced slippage and longer service life. Standard pumps operate to 250ºF and, with modifications, to 500ºF.

Helical gears provide very smooth and quiet operation at direct motor speeds in hydraulic, lubrication and transfer applications in almost every industry classification.

Foot Mounted Pump

SPECIFICATIONS
General
Design: Drive speeds to 1140 RPM; discharge pressures to 300 PSI;
   flow rates to 175 GPM; foot mounted
Material: Cast Iron casings with precision machined, heat treated gears
   and case hardened shafts. Pumps are also available in Ductile Iron.
Gears: Helical gears
Bearings: Anti-friction. Also available with iron or carbon graphite
   sleeve bearings.
Seal: Self adjusting mechanical seal with Buna-N elastomer. Also
   available with compression packing. Mechanical seal 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: Clockwise or counter-clockwise rotation. A reversible back
   drain permits direction of rotation to be easily changed in the field.
Liquid Viscosities: 100 SSU to 100,000 SSU. Adaptable for handling
   liquids of higher or lower viscosities.
Suction Lift: Up to 28" Hg / 31 feet depending on the type of liquid
   being pumped.
Drive Options: 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
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.
