Mono EZstrip Compact Z19 Pump
Spare Parts for EZstrip Compact Z19 Pump
Product Summary
The Mono EZstrip™ Compact Z19 is a revolutionary Maintain-In-Place (MIP) progressing cavity pump designed to eliminate costly downtime. Featuring a patented split suction chamber and split coupling rod, it allows for immediate access to the rotating assembly for de-ragging and maintenance without disconnecting pipework or electrical supplies, reducing service time from hours to minutes.
- Maintain-in-Place (MIP): Complete drive train (rotor, stator, shaft, rod, seal) can be removed in less than 4 minutes while the pump remains installed.
- Split Suction Chamber: Allows immediate access to clear ragging and blockages by removing just a few screws.
- Interchangeable Design: Can be retrofitted into existing Mono Compact C installations without modifying piping or baseplates.
- Split Coupling Rod: Innovative design separates the drive train components easily without disturbing the motor or gearbox.
- Pre-Assembled Drive Train: Optional ready-to-fit rotating assembly available to further minimize maintenance windows.

Troubleshooting, Common Faults & Solutions
Excessive build-up of rags (De-ragging)
Likely Cause: Ragging is common in waste water; EZstrip design mitigates downtime.
Action / Part: Remove suction chamber screws, split chamber, remove rags manually (2.5 mins).
No flow or low flow
Likely Cause: Worn stator, wrong rotation, or blocked suction.
Action / Part: Inspect Stator (Z18/Z19) for wear, check motor rotation.
Noisy Operation
Likely Cause: Worn universal joints or bearings.
Action / Part: Replace Joint Kit (Pin/Bush) or Drive Shaft Bearings.
Product leaking from pump
Likely Cause: Mechanical seal failure or loose flanges.
Action / Part: Replace Mechanical Seal or tighten suction chamber gaskets.
Pump vibrates excessively
Likely Cause: Misalignment or worn rotor/stator.
Action / Part: Check coupling alignment and inspect Rotor/Stator fit.
