Your Pump. Our Rotors. Better Performance.
With over 30 years of experience designing and manufacturing progressive cavity pumps, ROTOMAC offers a comprehensive retrofit spare parts programme for all major global brands — delivering equal or superior performance at significantly better value for money.
Manufacturing
Drop-In Replacement Parts for Any PC Pump
Progressive cavity pumps from global brands like Mono®, NETZSCH®, Moyno®, and Seepex® share the same fundamental rotor-stator principle — which means ROTOMAC can manufacture precision retrofit spares that fit directly into your existing pump housing, with no modifications required.
Our retrofit programme is specifically designed for plant operators and maintenance teams who want to reduce spare parts costs and improve pump reliability without replacing the entire pump unit.
We Have Retrofits For:
ROTOMAC retrofit spares are precision-engineered to fit the following global PC pump brands — and many others. If your brand isn't listed, contact us and we will assess compatibility.
Retrofit rotors, stators, couplings and wear parts for all Mono® progressive cavity pump series used across wastewater, food, and industrial applications.
Precision-fit replacement stators and rotors for Moyno® pumps commonly used in oil & gas, chemical, and municipal water treatment installations.
Drop-in retrofit spares for Allweiler® pumps serving marine, chemical processing, energy, and industrial fluid transfer applications worldwide.
High-quality interchangeable parts for NETZSCH® NEMO® series pumps widely deployed in sludge handling, mining, food production, and biogas facilities.
Replacement rotor and stator assemblies for Bellin® pumps used in demanding chemical, pharmaceutical, and specialty fluid transfer processes.
Sanitary-grade retrofit spares for Inoxpa® pumps operating in food & beverage and pharmaceutical applications requiring hygienic construction standards.

How to Order Retrofit Spares
Ordering the right retrofit spare is straightforward. We need just a few details about your existing pump to identify and manufacture the correct replacement parts.
Identify Your Pump
Locate the pump nameplate and note the make, model, and serial number. If available, share the existing rotor or stator part number.
Share Your Requirements
Tell us the fluid type, temperature, viscosity, and any special requirements such as hygienic grade, abrasion resistance, or chemical compatibility.
Receive Quotation
Our team will identify the correct retrofit and provide a quotation covering material, lead time, and delivery — usually within 24–48 hours.
Delivered to Your Door
Once confirmed, we manufacture and dispatch your retrofit spares with full documentation, packaging, and fast nationwide delivery.
Built Better. Priced Smarter.
There are many retrofit suppliers in the market. Here is why plant managers and maintenance engineers consistently choose ROTOMAC over both OEM parts and other alternatives.
Proven to Outperform OEM
The majority of our retrofit customers report longer service intervals, lower failure rates, and better overall performance compared to the original branded spare parts.
Precision-Engineered Fit
Every retrofit spare is reverse-engineered and manufactured to exact dimensional tolerances — ensuring a perfect drop-in fit with no housing modifications or adaptation required.
Significantly Lower Cost
Eliminate the OEM premium without sacrificing quality. ROTOMAC retrofits deliver the same or better performance at a fraction of the original manufacturer's spare parts pricing.
Full Material Flexibility
Unlike OEM parts which come in fixed material options, ROTOMAC can upgrade your rotor to a harder alloy or your stator to a better elastomer — improving performance beyond the original specification.
Fast Availability
With our Kanpur manufacturing base and nationwide branch network, ROTOMAC retrofit spares are manufactured and dispatched rapidly — minimising your pump downtime and production loss.
30+ Years of PC Pump Expertise
ROTOMAC has been designing and manufacturing progressive cavity pumps since the 1960s. Our engineers understand rotor-stator geometry as deeply as any OEM manufacturer in the world.
