Mono EZstrip Compact Z16 Pump
Spare Parts for EZstrip Compact Z16 Pump
Product Summary
The Mono EZstrip Compact (Models Z16) is a revolutionary progressing cavity pump designed for "Maintenance-in-Place" (MIP). Engineered to fit into compact spaces, it allows for the removal of the rotor, stator, and drive train assembly without disconnecting suction or discharge pipework, reducing maintenance time by up to 95% compared to standard PC pumps.
- Maintenance-in-Place (MIP): Unique split coupling and suction chamber allow full access to rotating parts without disturbing pipework.
- Compact Design: Reduced footprint makes it ideal for replacing standard pumps in tight installations.
- Gentle Pumping Action: Low shear operation preserves shear-sensitive fluids like sludge, emulsions, and polymers.
- Pre-Assembled Drive Train: The rotor, coupling rod, and drive shaft can be removed as a single unit for easy bench maintenance.
- Durable Construction: Available in cast iron or stainless steel with various elastomer stator options for abrasive or corrosive media.

Troubleshooting, Common Faults & Solutions
No flow / Pump running dry
Likely Cause: Empty suction tank or blocked suction line.
Action / Part: Stop immediately to prevent Stator burn-out. Check supply.
Low Discharge Pressure
Likely Cause: Worn Stator or Rotor (Slip).
Action / Part: Tighten tie rods (if applicable) or replace Stator (Item 22A) and Rotor (Item 25A).
Knocking Noise
Likely Cause: Worn universal joints or coupling rod.
Action / Part: Inspect the split coupling rod and sleeve (Items 26B, 26C, 26D) for play.
Leakage at Drive End
Likely Cause: Mechanical Seal failure.
Action / Part: Replace Mechanical Seal (Item 10A).
Leakage at Inspection Cover

Mono EZstrip Z16 spare parts: frequently asked questions
Which Mono EZstrip Z16 variant do I have?
The Z16 family includes the Z16A, Z16B, Z16D and Z16K. Each has a different stator, rotor, coupling rod and drive shaft. Check the model on your nameplate and select the matching variant in the parts list. If you're unsure, add a nameplate photo or serial number and we'll confirm before quoting.
What EZstrip-specific parts are listed for the Z16?
The EZstrip design uses split parts for maintenance in place. The list includes the split coupling rod (rotor side, 26B, and shaft side, 26C), the coupling rod sleeve halves (26D) and the suction chamber halves (23E). These let the rotor, stator and drive train come out without disconnecting the suction or discharge pipework.
What stator and rotor options suit the Z16?
Stators (item 22A) are nitrile as standard, with other elastomers to suit your fluid. Rotors (item 25A) are listed in hard-chrome or stainless. Both are specific to the variant. The troubleshooting guide links low discharge pressure to a worn stator or rotor and recommends replacing them.
Why are the Z16 parts listed by item number rather than part number?
The list uses item references from the Mono Compact EZstrip manual (OMMP/042/01). Parts are ordered by exact model plus item, not by a unique code. We confirm the exact build before quoting. Related models are on our Mono pump spare parts page.
