Nitrogen Charging Cart

Nitrogen Charging Cart

Haskel’s nitrogen charging cart is a mobile nitrogen solution that can be used in aviation ground support applications such as tire inflation, pressure gauge calibration, line flushing, charging landing gear struts and accumulators.  This nitrogen charging cart can also be used for the operation of pneumatic tools. The carts also enable operators to use all available gas in a bottle and still charge to final pressure.

Bootstrap Nitrogen Boosters Bootstrap Pump

Bootstrap Nitrogen Boosters

Bootstrap Nitrogen Boosters

Bootstrap Nitrogen Boosters are simple area ratio piston type boosters that automatically reciprocate when gas pressure, up to 150 psi, is applied to the large low pressure drive piston. This piston is directly connected to small high pressure pistons inside the booting sections of both ends of the drive. Each boost section contains integral inlet and outlet check valves thereby producing a pumping action.

Unregulated Nitrogen or Helium from a supply cylinder(s) is directly connected at maximum pressure to the boost sections. Nitrogen to the drive section is regulated to 115- 120 psi by the integral drive control system Wearing parts are low cost elastomers and self lubricating engineering plastics, all available in seal kits, are field replaceable with simple instructions and conventional hand tools. Both units are lightweight, 1-man-portable, weather resistant and operate in any position.

These Bootstrap Pumps, also known as Bootstrap Booster Units, are designed for operators of helicopters and/or small aircraft where a portable self-powered booster is needed for ground support. The primary application is to service the high pressure on-board Nitrogen or Helium bottles on helicopters equipped with emergency inflatable “Pop Type” floats. However, using either model to service other components needing high pressure Nitrogen such as shock struts and precharging hydraulic accumulators is also common.

Air Pilot Switches

Air Pilot Switches

Haskel’s air pilot switch is a pressure switch producing a pneumatic signal up to 150 psi at any sensing pressure within their adjustment range.  2-position poppet type air signal valve shifts from its normal position by a rod from the sensing end which first must overcome an adjustable force spring or air regulated dome loader. The signal valve may be piped normally open, normally closed (no flow), 3-way or 2-way depending on model.

Remote Air Adjusted “Remoteset” Air Pilot Switch

Sensing pressures to 60,000 psi; Air valve 3-way normally closed (no flow), 2-way normally closed (no flow), normally open (flow)

Externally Adjusted Air Pilot Switch

Sensing pressures to 25,000 psi; Air valve 3-way, 2-way normally open (flow) or closed (no flow).

Internally Adjusted Air Pilot Switch

Sensing pressures to 60,000 psi;  Air valve 3-way normally closed (no flow), 2-way normally closed (no flow), normally open (flow).

Haskel Gas Boosters

Haskel Gas Boosters

The Haskel gas booster line offers both hydraulic-driven and pneumatic-driven gas booster units.

The hydraulic driven gas boosters are ultrahigh pressure compressors that can withstand pressures to 16,000 psi. For easy seal replacement, they also feature a floating piston.

Other important features of the Haskel gas booster line include:

  • Over 15 models to choose from
  • Flow rates range from 0 to 400 SCFM
  • Pressure from 0 to 15,000 psi

The pneumatic-driven gas booster is available in a single acting, single stage configuration.  They are the smallest and lightest Haskel gas booster with pressure capabilities up to 39,000 psi. These gas boosters provide an economical means of boosting pressure for testing of small components and similar applications where volume is small and efficiency is not as important.
