Questions & Answers
Is this a genuine original part?
Yes, this is a genuine Johnson Pump (SPX FLOW) part, not an unbranded imitation. It ensures full compliance with original equipment manufacturer specs.
How do I know if it is compatible?
Check your existing impeller for a pin drive or "slotted" shaft. If your dimensions are 40mm wide and 19mm deep, this is the correct replacement.
What is the glycerine for?
The glycerine packet is included to lubricate the impeller blades and pump housing during installation. This prevents "dry-run" damage on the first engine start before the water reaches the pump.
