Centrifugal Pumps for Hygienic Process Lines
High-efficiency stainless-steel pumps for dairy, beverage and food processes — engineered for sanitary design, gentle product handling and reliable CIP/SIP. This page covers the widely used LKH family with key variants, plus SolidC, multistage options and utility-grade FM-OS/GM models.
LKH: Hygienic Centrifugal Pump
Designed for sanitary transfer of low- to medium-viscosity media with excellent hydraulic efficiency and cleanability. Front-loading service concepts help reduce downtime.
Typical sizes include LKH-5, 10, 15, 20, 25, 35, 40, 45, 50, 60, 70, 80 and 90.
Recommended Standard Configuration
- Stainless motor shroud & adjustable stainless legs
- Mechanical seal options: SSS (single), FSS (flushed), DMS (double)
- Seal faces: Carbon/Silicon Carbide (C/SiC); elastomers typically EPDM (project dependent)
- Full-size impeller (recommended when using VFD)
- Impeller safety screw to help prevent loosening on reverse rotation
Connection types commonly SMS or DIN unions; Tri-Clamp available per project.
Applications & Benefits
- Low-viscosity product transfer, CIP return, water/utility duties
- High efficiency → lower operating cost
- Gentle handling to protect product quality
- Easy maintenance with front-loaded seals
- Hygienic geometry with cleanable seals and smooth flow path
LKH Variants for Specific Duties
Specialized configurations for evaporators, filtration, validated environments, and hazardous areas.
LKHI
Designed for elevated inlet pressures (up to ~16 bar) while maintaining hygienic performance and seal reliability.
High inlet pressureHygienic
LKHPF
High-pressure, high-efficiency variant tailored to filtration and duties requiring higher discharge pressure.
High pressureFiltration
LKH UltraPure
Configured for biotech/pharma with enhanced documentation and cleanability for validated processes.
BiotechPharma
LKHex
Configured for hazardous areas and explosion-proof environments (ATEX-oriented builds).
Hazardous areasATEX
Other Centrifugal Families
Options covering cost-optimized hygienic duties, higher head requirements, and utility/general service tasks.
SolidC (Cost-Optimized Hygienic)
A practical choice for standard duties like CIP fluids, utilities and straightforward product transfer. Stainless shroud, adjustable legs and either external single or flushed seals. Designed with cleanable seals and smooth internal contours.
- Typical impeller sizes: ~140–220 mm (model dependent)
- Common in dairies, beverages, personal care, light chemical and water processing
Multistage LKH (e.g., LKH-110 / LKH-120/P)
Two to four stages for higher discharge pressures while keeping hygienic design. Sanitary versions feature stainless shrouds, adjustable legs and seal choices (single or flushed) with SiC faces; suitable where higher head is needed.
2–4 stagesHigh headSanitary options
FM-OS (Utility Hygienic)
Utility-grade centrifugal pump for food, pharma and chemical where 316L wetted parts are sufficient. Single mechanical seal (NBR elastomer by default), available with SMS or DIN connections; compact form with legs and shroud.
Utility316L wettedCompact
GM (Utility Stainless)
Compact centrifugal pumps for general transfer. GM-1/2 with reinforced nylon impellers (up to ~80 °C); GM-1A/2A with 316L impellers. Single mechanical seal (NBR); SMS/DIN connections.
