Jet HVBS712-103W Coolant Pump 1/8Hp 115/230V

The Jet HVBS712-103W Coolant Pump 1/8HP 115/230V is designed for compatible band saws equipped with a coolant system. This pump circulates coolant to the cutting area, helping reduce blade heat, improve cutting efficiency, and extend blade life during metalworking operations. A failing coolant pump can result in inadequate coolant flow and decreased cutting performance.

This part fixes the following symptoms:

• Coolant pump will not start during band saw operation.

• Weak coolant flow reaching the cutting area.

• Pump motor overheats after extended use.

• Excessive vibration or humming from coolant pump.

• Coolant circulation stops intermittently while cutting metal.

Coolant Pump Not Starting

Quick Check: Verify incoming voltage matches the 115/230V configuration of the coolant pump.

Fix Suggestion: Inspect wiring connections, power supply, and motor terminals for loose or damaged connections. Replace failed electrical components if necessary.

Prevention Tip: Regularly inspect electrical connections and avoid operating the band saw in damp conditions that may affect the motor.

Weak Coolant Flow

Quick Check: Check the coolant line and intake area for metal chips or debris blockage.

Fix Suggestion: Clean the intake screen, flush coolant lines, and refill the reservoir with clean coolant solution to restore proper flow.

Prevention Tip: Change coolant periodically and remove metal debris from the coolant tank after heavy cutting sessions.

Pump Overheating During Operation

Quick Check: Touch the motor housing carefully to determine if excessive heat buildup is occurring.

Fix Suggestion: Ensure the coolant pump is properly ventilated and not running dry. Continuous dry operation can damage internal motor components.

Prevention Tip: Always maintain adequate coolant levels before starting the band saw.

Excessive Noise or Vibration

Quick Check: Inspect the pump mounting hardware and impeller area for looseness or obstruction.

Fix Suggestion: Tighten mounting bolts and remove any debris interfering with the impeller rotation.

Prevention Tip: Clean the coolant system routinely to prevent sediment buildup inside the pump housing.

Customer Experience: A customer replacing the Jet HVBS712-103W coolant pump noticed immediate improvement in coolant circulation and cleaner cuts on steel stock.
