  If your Red Jacket Water Pump experiences insufficient product flow, several factors could be responsible. First, ensure that the bypass valve is set according to the pressure requirements outlined in the manual. Also, check the pump strainer to confirm it is not clogged. For 3-phase pumps, verify the direction of rotation by interchanging two pump wires at the box. Additionally, make sure that the fixed pressure relief valve is closed and sealed before setting the pressure to 45 psi (310 kPa). If the DEF is partially frozen in the piping system, continue dispensing DEF to thaw it out.

  If your Red Jacket Water Pump has no product flow, verify the pump is running. Ensure the circuit breaker and lockout switch on the control box are not in the Off or tripped position. Check for any restrictions in the piping system, confirming the correct flow direction of the check valve and proper setup of ball valves and plumbing in the sump. Also, ensure there is sufficient DEF in the tank, maintaining a minimum of 6 inches (150mm) above the pump strainer/inlet. If the DEF is frozen in the piping system (DEF freezes at +12°F [-11°C]), consider installing pipe heaters or a DEF recirculation system. For single-phase pumps, ensure the correct direction of rotation by interchanging the two pump wires to the capacitor.

Why does my Red Jacket CoreDEF Water Pump keep stopping and starting?
- G

  If your Red Jacket Water Pump stops and starts, it could be due to several reasons. Check the voltage during starting to ensure it is correct; a voltage boost transformer may be needed if the wiring cross-section is too small, causing a voltage drop. Also, measure the resistance between pump wires and inspect the pump cable and wiring to ensure they match the manuals, addressing any open circuits or incorrect wiring. Finally, confirm the pump has bypass flow as per manual requirements, and for 3-phase pumps, check that the heaters in the starter box are the correct size; for single-phase pumps, check the capacitor for opens or shorts if the motor protection trips.
