The Monas Pump BS30 Progressive Cavity Stator, manufactured by Monas Pump Co., Ltd. (South Korea) under the material specification "NBR White, Stainless Case", is an authentic OEM replacement wear component engineered specifically for progressive cavity pumps (also known as eccentric screw pumps or mono pumps) operating in sanitary food processing, beverage bottling, pharmaceutical, and hygienic cosmetic manufacturing facilities.

Operational Working Principle in Monas BS30 Pumps:
Monas progressive cavity pumps operate on the proven Moineau principle, utilizing the precise kinematic interference between a single external helical metal rotor and a double internal helical elastomeric stator. As the rotor turns eccentrically within the stator, a sequence of sealed, fixed-volume cavities continuously progresses axially from the suction inlet to the discharge port. This provides positive displacement conveyance that is exceptionally smooth, low-shear, non-pulsating, and directly proportional to rotational speed. The stator acts as the vital sealing boundary; its internal geometry, material resilience, and interference fit determine the pump's volumetric efficiency, discharge pressure capabilities, and flow stability.

Key Material Features & Operational Advantages:
- FDA Food-Grade White NBR Elastomer Lining: Formulated from high-purity virgin Nitrile Butadiene Rubber (NBR) in brilliant white, fully compliant with FDA and sanitary contact standards. White NBR provides exceptional resistance to animal fats, vegetable oils, greases, synthetic lipids, and mild acid/alkali sanitation detergents. It will not leach colors, plasticizers, or unwanted rubber odors into sensitive food, dairy, or pharmaceutical formulations.
- Superior Mechanical Abrasion & Tear Resistance: Engineered with high tensile strength and resilience, Monas NBR withstands heavy sliding friction against the hard chrome-plated or stainless steel rotor, providing long operational lifespans and resisting micro-tearing when handling viscous pastes containing soft suspended particles.
- Heavy-Duty Stainless Steel Outer Housing: The stator outer sleeve is precision-machined from high-grade stainless steel (AISI 304 or AISI 316), providing robust structural rigidity and resistance to corrosive chemical washdowns, moisture, and aggressive factory atmospheres.
- High-Integrity Rubber-to-Metal Bonding: Molded and vulcanized using advanced high-pressure injection systems combined with proprietary cross-linking bonding primers. This ensures the white NBR rubber remains securely bonded to the stainless steel sleeve, completely eliminating the risk of elastomer de-lamination or collapse under continuous operating differential pressures.
- 100% Genuine OEM Dimensional Compatibility: Machined to Monas Pump factory engineering tolerances, guaranteeing an exact fit with the BS30 rotor and pump housing. It installs directly without requiring mechanical modification or field re-engineering, minimizing maintenance downtime.

Typical Industrial Applications:
- Food & Beverage Processing: Pumping tomato paste, chili sauces, mayonnaise, mustard, honey, sugar syrups, chocolate paste, liquid cheese, curd, dairy cream, vegetable oils, and fruit concentrates.
- Pharmaceuticals & Cosmetics: Transferring skin creams, body lotions, toothpastes, shampoos, liquid soaps, medical ointments, cough syrups, and herbal extracts.
- Household Care Chemical Production: Metering detergents, fabric softeners, cleaning surfactants, and liquid packaging feeds.
- Automated filling and packaging lines requiring low-shear, drip-free, non-pulsating fluid conveyance.
