Ideal for testing very low pressure Range -0.4 bar to 0.4 bar (± 6 psi) >Portable, only 1.6 kg >Hand pump – uses air >Great stability and high resolution >Minimal maintenance >Hand-tight quick connectors
The 901 Low Pressure Test Pump is a hand operated pressure pump designed to generate pressures from -6 psi (-0.4 bar) to 6 psi (0.4 bar).
A high-quality screw press is designed for fine pressure adjustment, with an adjustment resolution up to 0.1 Pa (0.001 mbar).
The 901 makes use of an isothermal bellows chamber which is designed for reducing the possible effects of environmental temperature change.
Most pumps make use of a check valve (non-returning valve) and are not well insulated which will cause large fluctuations in pressure with a change in ambient temperature or when the unit is touched. The 901 does not use a check valve and is remarkably stable.
Two hand-tight connectors installed on the pump allow easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches. The 901 is an ideal comparison test pump for low pressure applications.
Designed for high pressure pneumatic or low impulse hydraulic applications requiring a narrow deadband and tamper-proof set point. Explosion proof hermetically sealed. (NEMA 4X, 7, 9 and 13).
Compact, adjustable pressure switch for high pressure hydraulic process applications. Choose the 231P when a selectable deadband is required. Weather Proof (NEMA 4X and 13).

Pressure gauge pigtail siphons are used to protect the pressure gauge from the effect of hot pressure media such as steam and systems that contain superheated vapour. U Type Siphons are suitable for vertical pipe mounting. Coil / Pigtail Siphons are suitable for horizontal pipe mounting. A gauge cock is generally connected between the pressure gauge and siphon for isolation. Contact Teltherm for further options and technical assistance.
The compact, ITT Neo-Dyn, Series 130PX pressure switch is well suited for hazardous or corrosive atmospheres and is field adjustable. Suitable for low to mid-range pressure applications. Six model options available with adjustable set point ranges from 2 to 170 psig on increasing pressure and 1 to 155 psig on decreasing pressure.
