700 Series Rotary Gear Pump

Clark Solutions
700 Series Rotary Gear Pump
Pressure to 2000 PSI, Flow to 5.0 GPM, Drive Speed to 1725 RPM

DESCRIPTION
700 Series pumps are high pressure pumps designed to provide quiet and efficient service at standard motor speeds. Typical applications are hydraulic and metering service.

The pumps are available in cast iron and ductile iron. They are designed to operate at speeds to 1725 RPM, pressures to 2000 PSI, and flow rates to 5.0 GPM. The standard seal is a lip seal and lubrication of the anti-friction bearings is accomplished by the circulation of the pumped liquid. All models are available with foot or flange mounting.

These pumps have an outstanding record for reliable performance and long life. 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 250°F and, with modifications, to 500°F.

700 Series Gear Pump

SPECIFICATIONS
General
Design: Drive speeds to 1725 RPM; discharge pressures to 2000 PSI;
   flow rates to 5.0 GPM; foot or flange mounted
Material: Cast Iron casings with precision machined, heat treated
   gears and case hardened shafts. Pumps are also available in
   Ductile Iron.
Gears: Spur gears
Bearings: Anti-friction needle roller bearings.
Seal: Lip Seal
Lubrication: Self-lubricating using the pumped liquid.
Rotation: Clockwise or counter-clockwise, specify at time of order.
Liquid Viscosities: 100 SSU to 1000 SSU. Clean liquids having good
   lubricating quality.
Suction Lift: Up to 28" Hg / 31 feet depending on the type of liquid
   being pumped.
Drive Options: A-Drive (pump connected to C-face motor with
   adapter bracket and coupling). A version of the A-Drive with
   a shorter, more compact bracket is also available.
Accessories: Repair Kits, 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
Lip seal provides an ample safeguard against liquid leakage and the entrance of air.

700 Series pumps are available direct coupled to a NEMA C-Face foot mounted motor.
This assembly, referred to as an A-Drive, ensures accurate alignment and requires less
space and is less costly than a pump and motor mounted on a baseplate.
