Types of centrifugal pumps in our range

InoxMIM has been designing and manufacturing pumping and mixing systems since 1997. Through our FluidMIM division we supply equipment for transfer, dosing and recirculation across food & beverage, cosmetics, pharmaceuticals, chemicals and oenology.

Every model is sized from your process data—flow rate, total head (TDH), viscosity, temperature, NPSHa and chemical compatibility—to guarantee hydraulic performance, hygienic compliance and mechanical reliability.

Design principles we apply when engineering a centrifugal pump

  • Wet-end materials in AISI 316/316L with hygienic finishes (Ra ≤ 0.8 μm on sanitary models).

  • Process connections to DIN 11851/11856, CLAMP, SMS, RJT, GAS threads and DIN 2576 flanges.

  • Sealing options: single or double mechanical seals (with thermosiphon systems where required) and ATEX configurations.

  • CIP/SIP integration, reduced NPSHr and, on specific ranges, solid-handling geometries to protect the product.

  • Energy efficiency through optimised impellers and IE3/IE4 motors, plus modular designs for fast maintenance.

Selected centrifugal pumps from our catalogue

A centrifugal pump converts the motor’s mechanical energy into kinetic energy and pressure via an impeller rotating inside a volute casing. Fluid enters at the impeller eye (low-pressure zone), gains tangential velocity, and is converted to differential head as it discharges through the volute.
This is the most widely used pump family in plants because it delivers high hydraulic efficiency, smooth, pulse-free flow, low maintenance and a competitive total cost of ownership.

Helicoidal-turbine centrifugal pumps (FL–CH)

FL–CH pumps use an open helicoidal impeller combining axial intake with centrifugal discharge. This geometry delivers a continuous, very low-shear flow and allows soft solids and aerated liquids to pass without clogging or hydraulic shock. The outcome is a stable flow that does not damage the product, even when it contains pieces, short fibres or foam.

When should you choose an FL–CH?

  • When the fluid carries suspended soft solids (fruit/vegetable pieces, granules, curd, seeds) that must not be broken.

  • Where natural aeration is present (wine remontage, whipped mixes, tanks with high return).

  • In applications that demand a gentle handling profile and minimal shear, avoiding phase separation or texture changes.

  • As a replacement for positive displacement pumps when lower maintenance and a higher continuous flow are desired.

Operating advantages

  • Stable flow without product damage: gentle pumping that preserves particle integrity and organoleptic properties.

  • Gas/foam tolerance: maintains pumping with entrained air, reducing the risk of intermittent cavitation.

  • Large hydraulic passage: open impeller and optimised casing to minimise blockages with semi-solid products.

  • Low pulsation and vibration: ideal for feeding heat exchangers, filters or fillers.

  • Hygienic construction (wetted parts in AISI 316L) with single/double mechanical seals and DIN/CLAMP connections; CIP/SIP-ready with ATEX options available.

Recommended uses

  • Food & beverage: pulpy juices, pulps and purées, particulate sauces, creams and ingredient suspensions.

  • Oenology: remontage and transfer of must/wine while preserving skins and soft solids; pumping from fermenters.

  • Dairy: curd, yoghurt with fruit, granular cheese; circulation in vats containing fragile solids.

  • Cosmetics: gentle exfoliants, gels with microspheres, emulsions with dispersed particles.

What are the technical advantages of InoxMIM centrifugal pumps?

Centrifugal pumps in the FluidMIM division are engineered with AISI 316L wetted parts and sanitary finishes on hygienic models, ensuring corrosion resistance, effective cleanability and compatibility with sensitive formulations. Impeller and volute hydraulics are optimised to extract maximum performance for the installed power, lowering NPSHr, mitigating cavitation and reducing energy consumption in continuous duty. The full range integrates with CIP/SIP routines and can be supplied with single or double mechanical seals—with thermosiphon systems where required—plus ATEX, FDA and EHEDG options on hygienic variants.

Mechanically, the pumps use a modular architecture to accelerate maintenance: standardised sleeves, seals, bearings and lanterns reduce spares inventory and downtime. In parallel, application-led customisation—by fluid viscosity, abrasiveness, pH and temperature, as well as sector regulations—allows precise selection of connections (DIN/CLAMP/flanged), impeller geometry and seal configuration for each installation. For a breakdown by families and variants, see the centrifugal pump manufacturer section.

In which industrial applications do centrifugal pumps fit best?

  • In food & beverage, centrifugal pumps are the first choice for transfer and recirculation of filtered sauces, syrups, oils and drinks, and for CIP services where continuous, low-shear flow is critical; hygienic versions protect product integrity and speed changeover cleaning between batches.

  • In cosmetics and pharmaceuticals, they handle low- to medium-viscosity creams, gels and emulsions to reactors, heat exchangers or fillers, combining stable flow with polished surfaces and seal options compatible with hygienic cleaning and sterility.

  • In chemical processing, they suit solutions, solvents, lightly filled resins, silicones and liquid polymers, where mechanical robustness and the chemical resistance of AISI 316/316L ensure service continuity.

  • In oenology, they cover must and clarified wine transfer, filter feed and cellar utilities, prioritising gentle hydraulics to limit aeration and cavitation.

  • And in water treatment, they handle chemical solutions, hypochlorite, coagulants and flocculants in dosing and recirculation loops, with configurations prepared for extended operation and rapid maintenance.

Centrifugal pumps FAQs

For accurate sizing we require: nominal flow rate, total dynamic head (TDH), fluid viscosity and density, temperature, pH/chemical compatibility, available NPSH (NPSHa), presence and size of solids/foam, the required connections (DIN/CLAMP/flanged/GAS), and the operating environment (CIP/SIP, ATEX, hygienic or industrial). With these parameters we define the hydraulic size, impeller, seal arrangement and motor.

Centrifugal pumps perform best on low to medium viscosities (as a guide 1–300 cP, depending on curve and duty point). Above that range—or where a fixed volumetric flow regardless of pressure is needed—evaluate gear pumps, progressive cavity pumps or peristaltics. If you must handle fragile solids with low shear, the helicoidal-turbine centrifugal (FL–CH) is an ideal centrifugal option.

Yes—with the right model. FL–CH pumps provide a large hydraulic passage and low shear, maintaining a stable flow with soft particles or entrained air (e.g., pulpy juices, must, curd, purées). For clean liquids or light traces, FLxxCI/FLUID units are preferable for efficiency.

FLUID adds AISI 316L wetted parts, sanitary finish (Ra ≤ 0.8 μm), geometries that reduce NPSHr, full drainability, and CLAMP/DIN 11851 connections compatible with CIP/SIP and EHEDG/FDA criteria.
FLxxCI prioritises robustness and industrial flexibility (broad connection options, impeller/seal variability) for utilities and general process duties.

Ensure NPSHa > NPSHr: minimise suction losses (short, larger-diameter suction line; few valves/elbows), control fluid temperature, place the pump as low as possible relative to the tank level, and avoid air ingress. When selecting, choose impellers and speeds that lower NPSHr and consider the FLUID range where the process allows.

Yes. We supply ATEX configurations (group/zone per classification), and all hygienic ranges can be integrated into CIP/SIP with single or double mechanical seals (with thermosiphon). We also tailor elastomers, seals and materials for chemical and thermal compatibility with your process.
