SUCTION LIFT
FEATURES
• Ductile iron construction with hardened steel shafts
• Stainless helical gears for quiet operation
• Two lip seals for added leak protection
• Self lubricating carbon bearings
• O-ring seal for maximum leak protection
• Durable temperature-resistant paint finish
• Easy field assembly to C-face motors
• Compact dimensions
These positive displacement external gear pumps will generate 23"
HG lift, a feature found to be essential for years of successful cycling. As a
general rule, place the pump as close to the liquid source as possible. For a
first start-up, the pump should be primed to avoid dry running. Minimum size
of the suction pipe is the size of the pump inlet port. For longer suction lines
(over 3 feet), the pipe size should be at least one size or two sizes larger
than the pump inlet port.
ROTATION AND RELIEF VALVE
GENERAL DESCRIPTION
Tailored specifically for wear resistance and long life in waste
cooking oil transfer/reclamation service. They are designed to handle
oil at elevated temperatures to 400 °F, at pressures up to 50 psi, and
at shaft speeds to 1750 RPM while tolerating warm water flush cycles.
Shafts are hardened steel. Gears are 416 stainless steel. Rugged
ductile iron housings incorporate body/gear lubrication grooves. High
grade carbon-graphite bearings are used. The compact dimensions
allow drop-in replacement for HYPRO - NG11 pumps.
DRIVE ARRANGEMENT
These close-coupled pumps mount directly to a full range of
NEMA and IEC C-face motors by means of a suitable adapter bracket. The pump drive shaft is connected to the motor shaft by a flexible
coupling. Complete pump and motor units are available.
Given the body/gear face lubrication slots, these pumps are unidirectional. The standard pump is set up for normal rotation (clockwise when
viewing the pump from the shaft end). Contact the factory if opposite rotation is required.
C994R1B2 is equipped with an integrated relief valve set up for internal
bypassing. 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 down stream 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.
SEAL
Superior to mechanical seal designs that cannot tolerate occasional particles. Two independently mounted fluorocarbon lip seals are
separated by an intermediate chamber. The chamber is filled with food
grade grease to lubricate the outboard seal. Pumps are conveniently
supplied with a grease fitting (an optional grease cup is available) to
allow the addition of lubricant to the chamber during operation.
