Air Operated Diaphragm Pump

OVERVIEW

Teryair aluminium constructed pumps are commonly combined with Neoprene, Nitrile or PTFE Elastomers. With these elastomers they are ideal for pumping of water and water-based fluids, non-aggressive fluids, oily fluids and fluids having low acidic or alkali concentrations
Aluminium Pumps offer a relatively low-cost solution to many pumping applications.
For this purpose, the main industries that choose Aluminium pumps are Paints, Marine, Mining, Ceramic and Wastewater/Pollution management.

Diaphragm Options ‘X’

Neoprene
Nitrile
PTFE

Approvals and Certifications

All Teryair pumps are CE marked and manufactured under an ISO 9001:2015 Quality system by SGS. All Teryair aluminum, Ductile iron, and Stainless Steel pumps are explosion-proof Certified (ATEX).

Diaphragm Options DP 12 ALX

Type of Diaphragm	Image	Typical Usage
Neoprene		An excellent general purpose diaphragm for use in non-aggressive applications such as water- based slurries, well water or sea water. Exhibits excellent flex life and low cost. Temperature range -18 C to +93 C (0 F to +200 F)
Nitrile		Excellent for applications involving petroleum / oil-based fluids such as leaded gasolines, fuel oils, non-synthetic hydraulic oils, kerosene, turpentine and motor oils. Temperature range -12 C to +82 C (+10 F to +180 F)
PTFE		Excellent choice when pumping highly aggressive fluids such as aromatic or chlorinated hydrocarbons, acids, caustics, ketones and acetates. Temperature range +4°C to +104 C (+40 F to +220F)
