CIP (Clean-in-Place) is the core sanitation guarantee system for the food industry, covering five key processes: alkaline & acid circulation, micro-dosing of sanitizers, high-temperature hot water delivery, external COP foam cleaning, and surface disinfection spraying. As the heart of CIP systems, pumps must withstand alternating strong acid & alkali corrosion, high-temperature media, precise metering and stable pressure output simultaneously. JONSN provides a full matching solution via its MPG, MRA, MRB and MRC series magnetic gear pumps.
Short service life due to alternating acid and alkali corrosionPumps are continuously exposed to hot alkaline solution (1.5%–2.5%) and nitric acid (0.5%–1%). Ordinary 304/316L pumps suffer pitting corrosion, cracking and perforation leakage within 6–12 months. Leaked acid and alkali will invalidate cleaning batches entirely.
Unstable sanitizer dosing concentrationConventional pumps deliver metering errors over ±5% at low flow rates, resulting in total concentration deviation up to ±10% when combined with pipeline fluctuations. Low concentration fails to achieve the required 5-log microbial reduction; excessive concentration causes chemical residue exceeding national standards, and peracetic acid corrodes the passive film on stainless steel.
Leakage risks during 85–95°C hot water circulationStandard seals soften and wear dry under high temperature, leading to hot water leakage. This wastes thermal energy, lowers cleaning temperature and triggers failed ATP tests. Large central CIP stations sustain annual losses over RMB 200,000 caused by seal leakage and downtime.
Unstable pressure for COP foam cleaningConventional diaphragm pumps generate pressure pulsation of ±15%, creating uneven foam density. Insufficient foam residence time leaves blind areas on equipment outer walls and conveyors, reducing cleaning coverage to only 70%–80%.
Wasted disinfectant & unreliable surface disinfectionFluctuating flow leads to incomplete spray coverage or excessive chemical runoff. Dairy production lines waste tons of sanitizer yearly, and disinfection results cannot be reliably traced.
Optional Hastelloy C-276 pump heads resist full pH range of 1–14 without pitting or stress corrosion. Mirror-polished 316L construction eliminates dead volume residue. Magnetic drive achieves zero leakage, and positive displacement design maintains steady flow regardless of fluid viscosity changes.
Micro-liter metering delivers repeat accuracy of ±0.2% with concentration deviation below ±2%. It supports proportional dosing synchronized with main pipeline flow. Low-shear design prevents decomposition of peracetic acid, and PEEK + 316L wetted parts resist oxidative sanitizers.
FFKM perfluoroelastomer seals withstand continuous temperatures above 200°C, suitable for long-term 85–95°C hot water delivery. Magnetic seals eliminate hot steam leakage, and flow remains unaffected by tank backpressure fluctuations. Models fit both small and large central CIP stations.
Outlet pressure fluctuation is controlled below ±1%, delivering uniform foam density with water-to-detergent ratio deviation under ±1%. Stable backpressure ranges from 0.3–0.8 MPa to fit various spray guns and foam generators.
MPG handles localized spot spraying (filling valves, nozzles), while MRA covers large-area spraying (conveyors, walls, drains). Stable outlet pressure ensures uniform atomization with no blind spots or excessive runoff. Magnetic sealing prevents leakage of flammable 75% alcohol vapor, and flow stability enables traceable daily consumption records compliant with HACCP.
Wetted components: 316L stainless steel or Hastelloy C-276 withstand full alternating acid & alkali CIP cycles.
FFKM O-rings comply with FDA 21 CFR 177.2600 and EU 10/2011, with no migrant substances released at temperatures above 200°C.
PEEK gear shafts meet FDA 21 CFR 177.2415 and GB 9685-2016, resistant to acid, alkali and hydrolysis.
Full magnetic drive without dynamic seals eliminates debris contamination from worn seals.
All MPG/MRA/MRB models tolerate 121°C SIP steam sterilization for 30 minutes, with no pump replacement required after CIP cycles.
Dead volume < 0.5 mL ensures ATP readings < 10 RLU post-cleaning, passing verification in one cycle without rework.
Optional Tri-Clamp / DIN 11851 sanitary connections; quick-disassembly design enables pump head removal within 3 minutes for easy annual maintenance.
Pump bodies withstand repeated thermal cycling (ambient → 85°C alkaline wash → 60°C acid wash → 95°C hot rinse → ambient) with thermal fatigue life exceeding 10,000 cycles.
Single MRA pump handles full alternating acid & alkali cycles without equipment switching. Hastelloy C-276 withstands pH 1 to pH 14 corrosion, and magnetic sealing eliminates leakage and crystallization at sealing surfaces, turning pumps from the highest-failure point into the most reliable component of CIP systems.
ppm-level sanitizer precision within ±2% via MPG’s 40 μL/r micro displacement, solving the compliance dilemma of insufficient sterilization or excessive chemical residues that traditional pumps cannot address.
Dual protection of FFKM high-temperature seals and magnetic drive eliminates leakage during 85–95°C hot water supply, cutting downtime for central CIP stations and uninterrupting production cleaning schedules.
Pressure pulsation suppressed below ±1% via multi-tooth positive displacement gearing ensures consistent foam density throughout COP cleaning. Foam adheres to complex surfaces for over 15 minutes, achieving full ATP-verified coverage with zero blind zones.
Stable nozzle pressure and non-drifting flow enable complete atomization without runoff, cutting annual sanitizer consumption by 2–3 tons for typical filling lines and supporting traceable disinfection records.
Full CIP/SIP compatibility with triple FDA/GB/EU compliant materials (316L, FFKM, PEEK), dead volume < 0.5 mL and ATP < 10 RLU, eliminating non-conformities during HACCP audits.
