The INOXPA SLR Sanitary Rotary Lobe Pump is a positive displacement pump designed for hygienic process applications where gentle handling and reliable flow are required. The pump is suitable for managing low to high viscosity fluids and can handle products containing fragile solids without damage.
Tri lobe rotors provide smooth, consistent displacement with minimal shear, making the SLR pump suitable for sensitive food, dairy and pharmaceutical products. Stable flow characteristics support accurate transfer, filtration and bottling processes.
Depending on size and configuration, the SLR range offers flow rates suitable for small process duties through to higher capacity applications, with differential pressures up to 16 bar.
The SLR pump is designed for use in hygienic processing environments across multiple industries.
Typical applications include product transfer, circulation, filtration support, bottling lines and general process duties.
Industries served include dairy, food processing, beverage production, cosmetics manufacturing, pharmaceutical processing and fine chemical handling.
The SLR pump is suitable for pumping a wide range of products, including milk, cream, yoghurt, cheese curd, sauces, syrups, chocolate, fruit preparations and marinades.
In cosmetics and pharmaceuticals, it is used for creams, gels, ointments, emulsions and similar viscous products that require hygienic handling.
The SLR pump is a bare shaft rotary lobe pump manufactured with a cast stainless steel pump casing and cover. All product wetted parts are produced from AISI 316L stainless steel to meet hygienic process requirements.
Internal surface finishes achieve Ra values of 0.8 microns or better, supporting effective cleaning and minimising product retention.
The pump is fitted as standard with a balanced external single mechanical seal manufactured from carbon and silicon carbide with EPDM elastomers. Alternative seal materials and arrangements are available to suit specific process conditions.
Selected configurations of the SLR pump are authorised to carry the 3-A symbol. Suitability for 3-A applications depends on pump configuration and selected options and should be confirmed during specification.
The hygienic design supports clean in place routines when correctly specified and installed.
The SLR pump is fully configurable to match application requirements. Available options include alternative mechanical seal materials, flushed or double mechanical seals, lip seals or gland packing, FPM or PTFE gaskets, heating chambers and pressure relief or bypass arrangements.
Additional options include bi wing lobes, vertical support, isolation cans, rectangular nozzles, multiple drive options, trolleys, control panels and a wide range of hygienic connection standards including Clamp, SMS, RJT and DIN.
ATEX compliant versions are available for hazardous area installations.
