Air-operated diaphragm pumps Type RFM and RFML

Product catalog summary
Overview: FLUX air-operated diaphragm pumps, specifically the RFM and RFML types, are designed for versatility across various industries. They are known for continuous operation, high safety, reliability, and cost efficiency. These pumps are self-priming, safe for dry running, and overload-proof, making them suitable for handling viscous, abrasive, and aerated liquids.
Specifications: Available in four model sizes (10, 15, 25, and 40), these pumps have maximum delivery rates from 1 to 375 liters per minute. Constructed from materials like Polypropylene (PP) and Polytetrafluorethylene (PTFE), they offer conductive versions for hazardous areas. The pumps feature vulcanized diaphragms with a metallic core and are easily dismantled for cleaning.
Material Compatibility: The pump housing materials, PP and PTFE, are suitable for corrosive and high-flammability liquids. Diaphragm, balls, and seals are made from NBR, EPDM, FKM, and PTFE, each offering specific temperature and chemical resistance.
Performance and Features: These pumps provide variable delivery rates by adjusting air pressure, high chemical resistance, and suitability for high temperatures. They are designed for a long service life with short stroke lifts and feature an easily accessible control valve without seals.
Technical Data: Each pump type has specific technical data, such as delivery rate, operating pressure, suction head, and maximum size of solids. For instance, the RFM 10 model has a maximum delivery rate of 30 l/min and an operating pressure of 7 bar.
Accessories: A variety of accessories are available, including pulsation dampers, pressure controllers with filters, stroke counters, and fittings, enhancing the pumps' safety and functionality.
Compliance and Safety: The RFML models are electrically conductive and comply with ATEX-Directive 2014/34/EU for hazardous areas, being explosion-proof and registered with PTB.
Specifications: The document details various connection types and materials for RFM pumps, including part numbers and weights. Materials include PP and PVDF, with connections from G 1 A to G 2 A and weights from 0.01 kg to 0.04 kg.
Procedures: Suction tubes are specified for RFM 10, RFM 15, and RFM 25 types, with thread connections at the bottom end. Hose nozzles and male thread connections are available with different immersion lengths and diameters.
Standards and Recommendations: Fittings for electrically conductive pumps are available upon request. The document describes the construction and function of FLUX air-operated diaphragm pumps, highlighting their positive displacement mechanism and maintenance-free design.
Function and Construction Features: The pumps consist of two pump housings and a control valve part, with diaphragms separating the liquid and air sections. Operation involves a selector shaft and a control valve, allowing continuous operation without special maintenance.
Company Overview: FLUX is globally recognized for high standards in pump technology, originating from the invention of the electric drum pump in 1950. The company offers a wide range of customizable products used in various industries, emphasizing long service life, economy, and safety. FLUX-GERÄTE GMBH supplies pumps to nearly 100 countries worldwide.
