PTFE Chemflo AODD pump compliant with FDA standards, machined from a solid block of virgin or antistatic PTFE, fully housed within a stainless steel casing, providing safe transfer of your hazardous liquids.Self-priming suction lifts (3.6 m/12 ft dry and 8 m/26 ft wet)Can run dryCapable of stopping/restarting against closed/open valve without pressure relief or damageEasy maintenance via Flotronic Pumps' 'One-Nut' quick strip technologyEasy air valve maintenance while pump is in-lineA range of connections from ½” to 3”Complies with ATEX directive up to Gas Group IICOptional diaphragm rupture detection system with instant pump shutdown alarm installation to keep product contamination-freeOptional high-temperature diaphragm allows a maximum operating temperature of 135 ºC (275 ºF)Air valves available in polypropylene, PTFE, and stainless steelA range of connections includes ANSI/DIN/BS flanges with PTFE raised face as standard. Other connections can be supplied on request.The latest designs eliminate costly internal air mechanisms normally associated with double diaphragm pumps, and no lubrication required.Material certification available on request (e.g.: 2.2 on wetted components).IMPRESSIVE FEATURES AND ADVANTAGES OF THE CHEMFLO RANGE HELP YOU:Maintain safety levels in hazardous environments and operationsReduce downtime and cleaning costsKeep operations running and profitableCHEMFLO PUMPS: WHEN SAFE TRANSFER OF YOUR HAZARDOUS LIQUIDS IS CRITICAL.The Chemflo range of PTFE air-operated double diaphragm pumps has been specifically designed to handle hazardous materials, including aggressive chemicals. The design is crucially based on an external stainless steel casing that supports and protects the main PTFE pump body, which is machined from a solid block of PTFE/Teflon, across a range of pressure and temperature variations. This ensures a perfect seal is maintained under all conditions.The diaphragms are PTFE or TFM with nitrile or EPDM backing. Balls and seats are made from FDA-approved USP Class VI and PTFE or TFM.All this makes the PTFE Chemflo ideal for chemical, pharmaceutical, and similar industries.Flotronic's unique One-Nut concept is particularly useful given the likely applications of Chemflo. The One-Nut double diaphragm pump design is a quick-maintenance, quick-strip concept that turns conventional pumps on their head. The fluid passes between the diaphragms directly through the center of the pump with air pressure operating on the outside. The pump is held together by a nut on the side opposite the external air valve.'One-Nut' allows in-line inspection/replacement of diaphragms in less than 15 minutes. The outer metal casing is another reason for the widespread use of Chemflo in the chemical and pharmaceutical industries. Others include Chemflo's ability, as an air-operated double diaphragm pump, to self-prime, run dry, operate with dead head, and handle solids.Like all Flotronic pumps, the Chemflo can be customized to suit any application or location. Considering environmental protection, diaphragm rupture protection systems and fully pneumatic alarm systems can be installed.A range of accessories is also available, including pneumatic pulsation dampeners and batch control counters.An optional 2- or 4-wheel trolley with guide handle makes the Chemflo easily transportable.APPLICATIONS:Chemical, pharmaceutical, and similar industriesPilot plants (often on sampling lines)As emergency pumps for hazardous chemical recoveryTechnical Specifications / Features:Self-priming suction lifts: 3.6 m (dry), 8 m (wet)Dry running capabilityStop/restart against closed/open valve without damageQuick maintenance with One-Nut technologyIn-line air valve maintenanceConnection sizes: ½” to 3”ATEX compliant up to Gas Group IICOptional diaphragm rupture detection and alarmOptional high-temperature diaphragm: up to 135 ºC (275 ºF)Air valve materials: polypropylene, PTFE, stainless steelStandard connections: ANSI/DIN/BS flanges with PTFE faceNo internal air mechanisms, no lubrication requiredMaterial certification available on requestDiaphragms: PTFE or TFM with nitrile/EPDM backingBalls/seats: FDA-approved USP Class VI, PTFE or TFMCustomizable for application/locationOptional pneumatic pulsation dampeners, batch countersOptional 2- or 4-wheel trolley for portability
