Gear Pumps Cast Iron

Gear Pumps Cast Iron
These pumps are bidirectional. The standard pump motor unit is set up for normal rotation (clockwise when viewing the pump from the shaft end). Reversing the motor rotation will reverse the “in” and “out” ports and also requires changing the relief valve location.

Gear Pump C990X

These pumps are bidirectional. The standard pump motor unit is set up for normal rotation (clockwise when viewing the pump from the shaft end). Reversing the motor rotation will reverse the "in" and "out" ports and also requires changing the relief valve location. C990RX2B1 is equipped with an integrated relief valve setup for internal bypassing. The relief valve must always be located on the discharge side of the pump. This relief valve is not intended to be a metering or flow control device. Its purpose is to function as a discharge pressure relief to guard against intermittent downstream system restrictions. Overheating can occur within 5 to 10 minutes if the discharge line is completely shut off. The relief valve is located on the discharge side of the pump. The pressure relief setting is not set at the factory. To increase pressure, turn the relief valve adjusting screw in a clockwise direction.

Gear Pump C990M

Tailored specifically for wear resistance and long life in pressurized heat transfer oil circulation service for plastic injection molding and other industries. They are industrial units designed to handle fluctuating temperature cycles pumping Therminol ®, Dowtherm ® , Paratherm ® and others at elevated temperatures to 450 °F, at pressures up to 100 psi, and at shaft speeds to 1750 RPM. Shafts are hardened steel. Gears are high-strength durable Fatigue Proof ® steel. Rugged ductile iron housings. High-grade carbon-graphite bushing style bearings and thrust plates are used. The shaft seal is a bellows style mechanical seal with fluoroelastomer elastomer bellows and o-ring and with carbon and ceramic wear faces. No stuffing box cooling necessary. Contact Factory for 550 °F option.

Gear Pump C991

Tailored specifically for wear resistance and long life in lubricating fluid service. They are designed to handle a wide range of fluids at temperatures to 400°F, at pressures up to 150 psi, and at shaft speeds to 1750 RPM. Viscous liquids require reduced shaft speeds. Standard Lubricating Fluid Service: Shafting is 303 stainless steel, gearing is steel. Rugged ductile iron housings. High grade carbon-graphite bushing style bearings are used. The Standard Mechanical Shaft seal is a stainless cased Nitrile elastomer bellows and O-ring with carbon and ceramic wear faces. An optional fluoroelastomer mechanical seal with carbon and ceramic wear faces is also available. Recommended liquid temperature range is 32°F to 225°F (Nitrile) or 400°F (fluoroelastomer).

Gear Pump C992

Tailored specifically for wear resistance and long life in lubricating fluid service. They are designed to handle a wide range of fluids at temperatures to 200°F, at pressures up to 150 psi, and at shaft speeds to 1750 RPM. Viscous liquids require reduced shaft speeds.

Gear Pump C992T

The pumps are tailored specifically for wear resistance and long life in both lubricating C992T and non lubricating C992T-F service. They are designed to handle a wide range of fluids at temperatures to 200F. The operating pressure limit for thin fluids, i.e. 33 SSU, is 75 psi at 1725 RPM an 65 psi for viscous 200 SSU fluids based upon the 1.3 HP motor configuration.

Gear Pump C993

Tailored specifically for wear resistance and long life in lubricating fluid service. They are designed to handle a wide range of fluids at temperatures to 200°F, at pressures up to 150 psi, and at shaft speeds to 1750 RPM. Viscous liquids require reduced shaft speeds. Standard Lubricating Fluid Service: Shafting is 303 stainless steel, gearing is ferrous (optional 416SS gears). Rugged ductile iron housings. High grade carbon-graphite bushing style bearings are used. The Standard Mechanical Shaft Steel is a stainless cased Nitrile elastomer bellows and oring with carbon and ceramic wear faces. An optional fluoroelastomer mechanical seal with carbon and ceramic wear faces is also available. Recommended liquid temperature range is 32oF to 200oF.
