| E16 | 300 m³/h | 6 bar |
| E20 | 420 m³/h | 6 bar |
Family reference values are for identification and comparison. Confirm the complete pump configuration and operating requirements before selecting replacement components.
E Range Construction & Service Identification
Documented E Range construction includes cast-iron and stainless-steel arrangements, with rotor and stator material options selected for the application. Flexishaft drive arrangements are associated with this family. When requesting parts, provide the full E-series model, number of stages, materials and any legible rotor or stator number.
Monoflo B Range Parts & Technical Reference
The B Range is a close-coupled progressing cavity pump family. Legacy documentation and replacement-part references include the following B-series designations.
| Model Family | Configuration | Identification Note |
|---|---|---|
| B021 | Close-coupled | Verify complete model and stage |
| B031 | Close-coupled | 1- and 2-stage references exist |
| B041 | Close-coupled | 1- and 2-stage references exist |
| B051 | Close-coupled | 1- and 2-stage references exist |
| B061 | Close-coupled | 1- and 2-stage references exist |
| B071 | Close-coupled | 1- and 2-stage references exist |
| B081 | Close-coupled | 1- and 2-stage references exist |
| B091 | Close-coupled | 1- and 2-stage references exist |
| B101 | Close-coupled | 1- and 2-stage references exist |
| B121 | Close-coupled | Verify complete model and stage |
B Range Pressure & Materials
Legacy B Range documentation identifies one-stage arrangements up to approximately 6 bar (87 psi) and two-stage arrangements up to approximately 12 bar (175 psi). Construction references include cast-iron/tool-steel and stainless-steel arrangements. Historical stator material codes include RA for nitrile and RR for natural rubber.
Pressure and material information is a family reference, not a substitute for verification of the individual pump.
Monoflo Merlin Parts & Technical Reference
Merlin pumps were produced in several configurations. Industrial element families include AA, AB, AC, AE, AF and AG. Additional Merlin references include compact close-coupled and open-throat arrangements.
| Merlin Element | Maximum Capacity | Maximum Pressure |
|---|---|---|
| AA | 2.4 m³/h | 10 bar |
| AB | 6.0 m³/h | 10 bar |
| AC | 16.0 m³/h | 10 bar |
| AE | 26.0 m³/h | 10 bar |
| AF | 37.0 m³/h | 4.5 bar |
| AG | 61.0 m³/h | 4.5 bar |
Other Merlin Configurations
Legacy Merlin references also identify close-coupled DA, DB, DC and DE elements and open-throat CB, CC, CE, CF, CG, CJ and CK elements. Because configuration details can materially affect fit, ACCA verifies the complete designation before supplying replacement components.
Replacement Parts for Mono & Monoflo Pumps
Rotors
Replacement rotors can be identified from the pump family, element size, stage arrangement, material and existing part number.
Stators
Stator selection requires the correct element geometry plus elastomer compatibility with the pumped fluid and operating conditions.
Drive & Service Components
Supported service components can include shafts, drive components, seals, packing, bearings, housings and related rebuild parts where verified.
How to Identify Monoflo Replacement Parts
For the fastest and most reliable identification, provide as much of the following information as possible:
- Complete Mono or Monoflo pump model from the nameplate
- Element size and number of stages
- Existing rotor, stator or service-part number
- Wetted-component material
- Stator elastomer, when known
- Photographs of the pump, nameplate and component
- Critical dimensions when the original marking is unreadable
If the pump has been rebuilt previously, a sample component or dimensional drawing can help confirm the correct replacement.
Monoflo Pump Applications
Progressing cavity pumps in these families have been used in municipal and industrial wastewater, sludge handling, pulp and paper, mining, chemical processing and other services involving viscous, abrasive or solids-bearing fluids. Component materials and elastomers must be selected for the actual fluid, temperature, pressure and duty.

Monoflo Pump Parts FAQ
What information should I provide for a Monoflo rotor or stator?
Provide the complete pump model, element size, stage count and existing component number whenever possible. Photos and dimensions are useful when markings are missing.
Can ACCA help identify a part when the original number is unreadable?
Yes. Identification can often be narrowed using the nameplate, pump configuration, photographs and component dimensions. Final selection should be verified before ordering.
Do different stator elastomers fit the same pump size?
Different elastomer compounds may be available for a given geometry, but compatibility depends on the pumped fluid, temperature and operating conditions. The elastomer should be confirmed as part of the replacement selection.
Are ACCA parts genuine Mono or Monoflo components?
No. ACCA Pumps is an independent aftermarket manufacturer and supplier of replacement components for supported Mono and Monoflo pump applications.
Need Monoflo Pump Parts?
Send the pump model, existing part number, photos or dimensions and ACCA will help identify the supported replacement.
Mono and Monoflo names and model designations are used for identification and compatibility reference only. ACCA Pumps is an independent aftermarket manufacturer and is not affiliated with or endorsed by the original equipment manufacturer.
