B-Series, Models 1, 2, 3 & 4 Rotary Gear Pumps

Clark Solutions
B-Series, Models 1, 2, 3 & 4 Rotary Gear Pumps
Particle Tolerant, Pressure to 200 PSI, Flow to 26.8 GPM, Drive Speed to 900 RPM

DESCRIPTION
Models 1, 2, 3 & 4 pumps are general purpose positive displacement gear pumps and are a good choice for a variety of recirculating, mixing and transfer applications.

The pumps are available in cast iron, ductile iron, and bronze. They are designed to operate at speeds to 900 RPM, pressures to 200 PSI, and flow rates to 26.8 GPM. The standard seal is a packing gland and lubrication of the replaceable sleeve bearings is accomplished by the circulation of the pumped liquid. All models are available with foot or flange mounting and with integral relief valves.

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") This results in a pump with better lift, reduced slippage and longer service life. Further, the pumps are designed to be particle tolerant and will pass particles to 25 micron in size. Standard pumps operate to 250°F and, with modifications, to 500°F. Typical applications include abrasive materials, solvents, resins, and petroleum.

B Series Gear Pump

SPECIFICATIONS
General
Design: Drive speeds to 900 RPM; discharge pressures to 200 PSI;
   flow rates to 26.8 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, Bronze and Carbon Steel.

Spur gears are rugged and accurately cut and are a
favorite in machine hydraulic drives, lubrication and
coolant applications as well as in many other industries,
including textile, printing and plastic.

Gears: Models 1,2 & 3, spur gears; model 4, helical gears
Bearings: Replaceable iron sleeve bearings. Also available with carbon
   graphite or bronze bearings.
Seal: Compression packing with adjustable gland. Also available with
   self adjusting mechanical seal or lip seal. Mechanical seal and lip seals
   available with different elastomers.
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.
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. Duty: Light, medium & intermittent service
Drive Options: 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
Compression packing provides an ample safeguard against liquid leakage and the entrance of air.
PARTICLE TOLERANT
Low rotational speed and attention to gear tolerances allow particles to 25 microns to pass through pump.

Delivery and horsepower are based on liquid viscosity if 300 SSU at speed and pressures shown.

Foot and Flange Mounts

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.

B-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.
