Stainless Steel Pump

Sanitary & Pharmaceutical Stainless Steel Pumps | Clean-In-Place (CIP) Fluid Handling

Vertical Overview & Sanitary Design Standards

Engineered specifically for aseptic processing, pharmaceutical fluid transfer, and high-purity food and beverage lines. Constructed from medical-grade 316L stainless steel to prevent microbial growth, withstand aggressive Clean-In-Place (CIP) and Steam-In-Place (SIP) cycles, and eliminate product entrapment zones.

Target Media

Purified water (WFI), parenteral solutions, biological media, liquid food ingredients, and cosmetic emulsions.

Wetted Material

AISI 316L (low carbon, controlled sulfur content <= 0.015% for superior weldability and corrosion resistance).

Surface Finish

Mechanically polished and electropolished wetted surfaces achieving an internal roughness of Ra <= 0.4 um (15 microinch) or mechanically polished to Ra <= 0.8 um.

Connection Standards

Tri-Clamp (ISO/BS), DIN 11851, SMS, and aseptic flange connections designed to eliminate dead legs.

Sanitary Selection & Hydraulic Parameters

Match your sterile process requirements against our sanitary centrifugal and positive displacement profiles. Designed to ensure gentle handling of shear-sensitive biological products.

Manufacturing, Electropolishing & Quality Verification

Orbital Welding & Casing Design: Internal hydraulic casings feature self-draining geometry with zero dead-legs; all structural tubing joints utilize automated orbital TIG welding with internal argon purging.

Electropolishing (EP): Electrochemical treatment performed on wetted components to remove microscopic surface peaks, reduce surface energy, and passivate the chromium-oxide protective layer.

Elastomer Compliance: All static and dynamic O-rings, gaskets, and seals conform strictly to FDA 21 CFR 177.2600 and USP Class VI biological reactivity standards (PTFE, EPDM, FKM, or Silicon).

Hydrostatic & Cleanliness Testing: Every pump undergoes pressure decay and pressure retention testing, coupled with optical surface roughness (Ra) verification using stylus profilometers.

Traceability & Compliance Docs: Full material traceability packages supplied, including EN 10204 3.1 MTRs, FDA conformity letters, and USP Class VI certificates.

Technical RFQ Data Requirements

To generate a formal technical proposal, hygienic data sheet, and quotation within 24 hours, provide the following operational parameters:

Fluid Characteristics

Product name, viscosity, specific gravity, and temperature during operation and during CIP/SIP cycles (up to 140°C).

Hydraulic Duty Point

Required flow rate (Q) and Total Dynamic Head (H).

Regulatory Requirements

Specific standard compliance needed (e.g., 3-A Sanitary Standards, EHEDG, FDA, or cGMP).

Motor & Electrical Spec

Washdown duty motor (IP55/IP66, TEFC or Inverter Duty) and voltage/frequency.

Frequently Asked Questions (Sanitary Pump Focus)

Q: How do you ensure cleanability and prevent bacterial growth inside the pump casing?

A: Cleanability is achieved through strict geometric design: eliminating internal sharp corners and dead legs, utilizing self-draining casing architecture with vertical discharge orientation, and applying an electropolished internal surface finish of Ra <= 0.4 um. This minimizes biofilm adhesion and ensures complete residue removal during Clean-In-Place (CIP) cycles.

Q: Can these pumps withstand high-temperature Clean-In-Place (CIP) and Steam-In-Place (SIP) procedures?

A: Yes. Standard sanitary configurations accommodate fluid and cleaning temperatures up to 95°C for continuous CIP, and up to 140°C for short-duration Steam-In-Place (SIP) sterilization cycles. Elastomers such as EPDM and PTFE are specifically selected to resist steam degradation and thermal cycling fatigue.

Q: What certifications are provided to verify compliance with pharmaceutical and dairy standards?

A: Our sanitary pumps are manufactured in accordance with 3-A Sanitary Standards and EHEDG (European Hygienic Engineering & Design Group) guidelines. Each unit ships with FDA compliance declarations, USP Class VI elastomer certificates, and EN 10204 3.1 material test reports.

Q: How do you prevent contamination of the pumped fluid from the mechanical seal area?

A: We utilize flushable single or double mechanical seal configurations designed with balanced faces and external flushing loops. In critical biotech applications, double mechanical seals are paired with a sterile barrier fluid (such as WFI or clean steam condensate) to ensure that any potential leakage path moves outward away from the product stream.

Q: Are the electric motors suitable for washdown environments in food processing plants?

A: Yes. Standard motors supplied for sanitary applications feature moisture-resistant windings, corrosion-resistant cast iron or stainless steel frames, and carry an IP55 or IP66 ingress protection rating to withstand high-pressure, caustic washdown cleaning regimens common in food and beverage facilities.

Q: What is the standard lead time for standard sanitary pumps vs. custom builds?

A: Standard catalog sanitary centrifugal pumps with common Tri-Clamp connections and stock motors ship within 2 weeks. Custom-configured positive displacement lobe pumps or units requiring specialized explosion-proof (Ex-proof) motors typically require 3 to 5 weeks.
