Product Description:
The Sera GMBM174-4CFW pump diaphragm is a premium-quality replacement membrane designed for SERA (SaiNuo) mechanical metering pumps. SERA is a German family-owned enterprise headquartered in Immenhausen, Germany, with a history dating back to 1945. The company is a leading German manufacturer in the dosing and compressor technology fields, producing serum metering pumps, serum transfer pumps, valves, PTFE diaphragm compressors, and metal diaphragm compressors.
This diaphragm is manufactured from a high-performance rubber and PTFE (polytetrafluoroethylene) composite material. The PTFE layer provides exceptional chemical resistance and a non-stick surface, while the rubber backing offers flexibility and durability. This combination ensures reliable sealing performance, long service life, and resistance to a wide range of aggressive media.
SERA metering pumps are designed as zero-leakage positive displacement pumps. They are engineered for the precise, safe, and economical dosing of difficult fluids in demanding industrial applications. This replacement diaphragm is a critical component for maintaining the pump's metering accuracy, safety, and operational reliability.
This diaphragm is available in multiple diameters, including 175mm, 145mm, and 110mm, to suit different SERA pump models and flow requirements.

Applications:
Water & Wastewater Treatment
Chemical dosing plays a crucial role in water and wastewater treatment processes. It is used for flocculation, pH adjustment, disinfection, and coagulation to ensure the purification and safety of water.
Cooling Water Circuits
In cooling water systems, disinfectants and various additives are carefully dosed to maintain system efficiency and prevent microbial growth.
Chemical Processing
This sector requires precise metering of acids, alkalis, solvents, and other aggressive chemicals to support various manufacturing operations safely and effectively.
Pharmaceutical Manufacturing
Pharmaceutical production demands accurate dosing of active ingredients and process fluids to guarantee product consistency and compliance with strict regulatory standards.
Food & Beverage Processing
Sanitary chemical dosing using compatible materials is essential in the food and beverage industry to maintain hygiene and ensure the safety of consumable products.
Paper & Pulp Industry
In paper and pulp manufacturing, additives and bleaching chemicals are dosed to enhance product quality and optimize production processes.
Plastics Manufacturing
The plastics industry utilizes chemical dosing for additives and processing aids to improve material properties and manufacturing efficiency.
Electroplating & Surface Finishing
Chemical baths and rinse water are controlled through precise dosing to achieve desired surface finishes and maintain environmental compliance.
Power Generation
Chemical injection for boiler feed water treatment is critical in power generation, preventing corrosion and scaling within the system.
Oil & Gas
Chemical injection is widely used in oil and gas production and processing to enhance efficiency and protect equipment from corrosion and fouling.
Packing and Shipping:
Each Pulse Valve Diaphragm is carefully packaged to ensure maximum protection during transit. The diaphragm is first wrapped in anti-static and moisture-resistant material to prevent any damage or contamination. It is then placed in a sturdy, custom-fitted box designed to minimize movement and absorb shocks.
For shipping, we use reliable carriers with tracking options to guarantee timely and secure delivery. Bulk orders are palletized and shrink-wrapped to provide additional stability. All packages are clearly labeled with product information, handling instructions, and safety warnings to facilitate smooth processing and handling.
Our packaging and shipping processes are designed to maintain product integrity and provide customers with a seamless and satisfactory purchasing experience.
