Lifting of Pump
DO NOT LIFT, CARRY OR HANG
PUMP BY THE ELECTRICAL
CABLES. DAMAGE TO THE
ELECTRICAL CABLES CAN CAUSE
SHOCK, BURNS OR DEATH.
• Lift the pump with an adequately sized chain or cable
attached to the lifting handle (458). DO NOT damage
electrical cables while raising and lowering unit.
Sliderail System
• The OPTIONAL Goulds Model A10-20 sliderail system is
recommended for proper installation.
NOTICE: FOLLOW THE INSTALLATION AND
OPERATION INSTRUCTIONS PROVIDED
WITH THE SLIDERAIL SYSTEM.
• Installation of the sliderail system should locate the pump
opposite the influent opening, preventing stagnate areas
where solids can settle.
• The pit floor MUST be flat under the sliderail base and
have sufficient loading capacity to support the entire
weight of the assembly, including the sliderail base,
sliderail guide, pump and all assorted piping.
Piping
• Discharge piping should be no smaller than 2" (51 mm)
diameter and kept as short as possible, avoiding
unnecessary fittings to minimize friction losses.
• Install an adequately sized check valve (suitable for
handling
3
4" (19 mm) solids for effluent applications and
2" (50 mm) solids for sewage applications) in the
discharge pipe to prevent backflow. Follow the check
valve manufacturer’s installation instructions.
• Install an adequately sized gate valve ABOVE the check
valve for pump, plumbing and check valve maintenance.
• To deter air locking, drill a
3
16" (4.8 mm) hole, 2"
(50.8 mm) beyond the pump discharge connection.
• All piping must be adequately supported, so as not to
impart any piping strain or loads on the pump.
