TDA Pumps

Air driven, high volume, high pressure, TDA pumps to 21,600psi

Typical Applications

• Pressure testing of large i.d. pipelines, hose umbilicals, wellhead control valves...
• Chemical injection including methanol and glycol
• Pre-charge of hydraulic accumulators
• Operation of Sub-Sea Valves
• Pre-fill and pre-pressurisation of high pressure and high volume test systems

Features

• Ability to stall at any predetermined pressure and hold this pressure without consuming power or generating heat
• Infinitely variable cycling speed and flow
• Reliable, easy to maintain, compact and robust
• Dual seals between hydraulic and air sections with captured vent port as standard

Construction Materials

• Hydraulic Section - Mainly stainless steels with water and/or oil service duty seals
• Air Drive Section - Mainly anodised aluminium with Buna N seals
• Special Seals for handling special fluids or chemicals are available
