Air Driven Pump Unit

Approximate size – 42cm x 42cm x 45cm
Weight (reservoir empty) – 22.5kg
Reservoir capacity – 9 litres
Hydraulic piston diameter – 6.35mm
Hydraulic piston area – 31.67mm²
Volume per stroke – 999.6mm²

Air Consumption

When operating from zero to rated hydraulic pressure, air consumption will be approximately 28ft³/Min of free air at 100 PSI input. At lower air pressures and higher hydraulic pressures, air consumption will be reduced proportionally to flow rates included.

Air Pump

Tentec Mini Air Driven Pump Unit

Tentec Air Driven Pump Units operate on the simple but efficient principle of power magnification through the use of differential areas. A relatively large air-operated piston drives the smaller piston, which provides fluid flow at high pressures. All Tentec air driven pump units are fitted into an easily transportable, tubular steel frame.

The pump units are available, fitted with a large choice of pressure gauges and are supplied complete with an air pressure regulator which can be set to stall the pump unit when it reaches the pressure required for each particular tensioning application.

Technical Specifications

Tentec supply many different air driven pump units, of varying pressure and fluid discharge specifications.

This document details the main tensioning air pump, the model HTT.627x Series.

The Tentec standard tensioning pump configuration is the model HTT.6271, with a maximum working pressure of 1500bar fitted with a suitable gauge and outlet connection.

For higher pressure needs the model HTT.627x series pump can be configured with a 2275bar max working pressure, fitted with a suitable gauge and outlet connection. Part number HTT.6272
