Page 4: Safety
SAFETY Pump installations are seldom identical. Each installation and application can vary due to many different factors. It is the owner/service mechanics responsibility to repair, service, and test to ensure that the pump integrity is not compromised according to this manual. -
Page 5: Inspection
Give it to the owner or affix it to the control panel when finished with the installation. If anything appears to be abnormal, contact your BJM Pumps® distributor or Industrial Flow Solutions Operating, LLC. If damaged, the pump may need to be repaired before use. -
Page 6: Oil Fill Quantity/Type
• Check the oil in seal chambers prior to startup to ensure oil is moisture free and has not broken down. • Megger the motor prior to startup. The reading should be above 100 MΩ. • Remove the air check screw on the motor housing. Using an air compressor, pressurize the motor chamber to 13 psi and check for leaks using a spray bottle. -
Page 7: Positioning The Pump
Do not lift the pump by the power cable or discharge hose/piping. Proper lifting equipment (rope/chain) must be used. POSITIONING THE PUMP BJM Pumps® SKGF Series pumps are designed to operate fully or partially submerged. Avoid running the pump dry. Refer to data sheet for minimum submersion depth for your particular model. -
Page 8: Pump Operation
2. Since the impeller cannot be seen, the best way to check the rotation is to check the kick back motion of the pump when the pump just starts. The kick back motions should be viewed from the top. The kick back motion of the pump should be counter clockwise as shown in the picture above. -
Page 9: Stopping
For manual operation: 208, 230, 460 & 575 volt: Attach the proper plug, connect directly to the power source or control box. Check the direction of the rotation. Tilt the pump and start it. It should twist in the opposite direction of the arrow (on pump). It is recommended that a Ground Fault Interrupter (GFI) type receptacle (or equivalent) be used. -
Page 10: Typical Municipal Or Industrial Wastewater Installation
TYPICAL MUNICIPAL OR INDUSTRIAL WASTEWATER INSTALLATION NOTE: Maximum recommended starts should not exceed 10 times per hour. AUTOMATIC OPERATION Three phase pumps need a separate control box with float(s) for automatic operation. STOPPING To stop the pump (manual and automatic mode), unplug it from the power source, turn off the breaker, or turn the power source off (generator). -
Page 11: Intended Methods Of Connection
Use with approved motor control that matches motor input in full load amperes. “UTILLISER UN DÉMARREAR APPROUVÉ CONVENANT AU COURANT Á PLEINE CHARGE DU MOTEUR.” BJM Pumps has been evaluated for use with water or water based solutions. Please contact the manufacturer for additional information. -
Page 12: Three Phase Wiring Instructions
THREE PHASE WIRING INSTRUCTIONS FOR YOUR PROTECTION, ALWAYS DISCONNECT PUMP FROM ITS POWER SOURCE BEFORE HANDLING. “Risk of electrical shock” Do not remove power supply cord and strain relief or connect conduit directly to the pump. Installation and checking of electrical circuits and hardware should be performed by a qualified licensed electrician. -
Page 13: Pump Will Not Run
PUMP WILL NOT RUN 1. Check power supply (fuses, breaker). Reset power. 2. Blocked impeller. Check and clean. 3. Defective cable or incorrect wiring. 4. Float switch tangled/obstructed. Clean and free float switch from obstruction. 5. Float switch defective. Replace float switch. 6. - Page 14 S/SX/J/JX/R/RX/KZN/KB/KZE model pumps, BJM Pumps offers an impeller shim kit. The shims are designed to go on the shaft behind the impeller to adjust the clearance between the impeller vane and the suction cover to the target specification of the 0.010 inch to 0.020 inch.
- Page 15 9. Install the suction cover applying the proper torque to the remaining fasteners. 10. Using the angled set of feeler gauges, recheck the impeller clearance in various locations. The measurement should fall between the 0.010 inch and 0.020 inch specification. Caution, to not allow the clearance to be less than 0.010 inch since this may cause undesirable rubbing of the impeller on the suction cover.
- Page 16 Radial shredder ring installed. M3 hex socket fastener with 242 (blue) Loctite.
- Page 17 The shredder rings installed in the housing and retained with the four M3 screws. 2. Impeller Shimming – With the volute installed on the motor, the impeller is added to the shaft. The suction cover is then added without the shredder housing in place.
- Page 18 Feeler gauge shown between impeller vane and top of suction cover. 3. Installing the Shredder Housing – First apply a light coating of the Jet Lube Marine Grade Anti-Seize to the shredder housing threads. Next thread the housing into the suction cover until the housing has hit the bottom of the threads. Add a light coating of the Jet Lube Marine Grade Anti-Seize to the inside threads on the shredding cutting bar.
- Page 19 The shredder cutting bar should be tightened to the proper torque using the special socket tool on an impact driver. Once the shredder cutting bar has been tightened to the shaft, verify that it can spin freely. The cutter elements are sharp, so care should be taken not to cut fingers.
- Page 20 4. Shredder Cutting Element Adjustment – With all of the elements installed, the housing should be rotated counter clockwise until the stationary axial cutting ring is tight against the shredding cutter bar (and the housing will not turn any more). Align the center of one of the stand mounting bosses with one of the 5 degree markers cast into the shredding housing.
- Page 21 Rotate the shredder housing clockwise 6 markers. Thread the locking screws down until contact is made with the suction cover. Tighten ¼ turn.
- Page 22 The BJM Pumps® “F” Series designed pumps utilize unique construction methods and materials. The interconnection of all wiring requires the use of a BJM Pumps® wire connection kit. Included in this kit are specific instructions on how a qualified factory trained and certified repair technician can perform this work properly.
