CHEMFLO PUMPS – WHEN THE SAFE TRANSFER OF YOUR HAZARDOUS LIQUIDS IS PARAMOUNT.

The Chemflo range of PTFE air operated double diaphragm pumps have been specifically designed to handle your hazardous materials including aggressive chemicals. Crucial to the design is an outer Stainless Steel housing which supports and protects the main PTFE pump body which is machined from a solid block of PTFE / Teflon, through a range of pressure and temperature variations. This ensures a perfect seal is retained under all conditions.

Diaphragms are PTFE or TFM faced with Nitrile or EPDM backing, Balls and seats are all manufactured from USP Class VI and FDA approved PTFE or TFM.

All making the PTFE Chemflo Ideal for chemical, pharmaceutical and similar industries.

Flotronic’s unique One-Nut concept is particularly useful given the Chemflo’s likely applications. The One-Nut design of double diaphragm pump is a fast maintenance, fast strip down concept that turns the conventional pump inside out. Fluid passes between the diaphragms directly through the centre of the pump with air pressure operating on the outside. The pump is held together by one 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 housing is a further reason for the Chemflo’s extensive use in the chemical and pharmaceutical industries. Others include the Chemflo’s ability, as an air-operated double diaphragm pump, to self-prime, dry-run, dead-head and handle solids.

Like all Flotronic pumps, the Chemflo can be customised to suit any application or location. With environmental protection in mind, Diaphragm Rupture Protection and fully pneumatic Alarm Systems can be fitted.

A range of accessories is also available including Pneumatic Pulsation Dampers and Batch Control Counters.

An optional 2 or 4 wheeled trolley with guide handle makes the Chemflo easily transportable.

 

APPLICATIONS:

  • Chemical, pharmaceutical and similar industries
  • Pilot plants (often in sampling lines)
  • As emergency pumps for hazardous chemical recovery.
