Safety Precautions for ATEX Pumps CAUTION: Proper o-ring material must be chosen for the fluid being pumped. Improper material selection could lead to swelling and be a possible source of leaks. This is the responsibility of the end user. WARNING: The pump must be checked for leaks on a regular basis. If leaks are noticed, the pump must be repaired or replaced immediately. WARNING: The pump must be cleaned on a regular basis to avoid dust buildup greater than 5 mm.
AC6 & 8 Assembly, Installation and Operation Unpacking and Inspection • Unpack the pump and examine for any signs of shipping damage. • If damage is detected, save the packaging and notify the carrier immediately. Section I - Assembly Tools Required: Metric box wrench set & metric deep well socket set - Pumps with Motors 1. No assembly required. Unpack the pump and motor and examine for any signs of shipping damage. If damage is detected, save the packaging and notify the carrier immediately. 2.
Section II - Installation Pump motor base should be securely fastened to a solid foundation. CAUTION: The NPSH available to the pump must be greater than the NPSH required. NPSH available should be two feet (.6 meters) greater than NPSH required. • Install the pump as close to the suction source as possible. • Support the piping independently near the pump to eliminate any strain on the pump casing. In addition, the piping should be aligned to avoid placing stress on the pump casing.
Flush Systems CAUTION: Some fluids react with water; use compatible flushing fluid. 1. Turn off the pump. 2. Completely close the suction and discharge valves 3. Connect flushing fluid supply to flush inlet valve. 4. Connect flushing fluid drain to flush drain valve. 5. Open flushing inlet and outlet valves. Flush system until the pump is clean.
Reassembly 1. Lubricate the rubber portion of the new stationary seal (item 5) with P-80 (or equivalent) or use soapy water. Do not use petroleum products to lubricate the rubber. Note: Keep the polished surface of the seal face clean. Use a piece of cardboard to protect the seal while pressing against the stationary face. 2. Press the stationary seal into the seal seat of the back head assembly so that the seal surface points away from the motor face. Place the back head into the motor adapter. 3.
