SC Hydraulic Engineering Corporation

90 Series Portable Test Cart

General Product Information
- PRESSURES UP TO 65,000-PSI
  ONLY 2 CONNECTIONS REQUIRED
  MOBILE SELF CONTAINED POWER UNIT
  5 OR 10 GALLON STAINLESS STEEL RESERVOIR
  AVAILABLE WITH ALL 10-SERIES PUMP MODELS
  PRESSURE GAUGES, VALVES AND AIR DRIVE CONTROLS INCLUDED
  
  The 90 Series Dual pump portable test cart is equipped with air controls, high pressure gauge, return line, 5 and 10-gal reservoir available, inline check valve to protect low pressure pump, local air drive shut-off valve for independent operation and pump hand attachment for precise testing.
  
  The included air exhaust muffler provides for quiet operation while ease of control during operation is achieved with a manual valve on one of two pressure ports. Pressures up to 65,000 psi can be achieved by using any of our 10 series pumps and a 100 psi air supply.
  
  10-5 pump configurations include a liquid filled, 31/2" dial gauge for ratios up to 280:1. For 10-6 units, the same gauge is included for ratios up to 240:1.
Applications
- Burst testing
  Water-jet blasting
  Hydrostatic testing
  Hydraulic press operation
  Hydraulic cylinder and valve actuation

Dimensions

* Coned and threaded high pressure connection for 1/4" O.D. tubing.

** Consult factory if gauge is desired.

Modifications

A Models:These models utilize dual seals in the hydraulic assembly with a bleed-off between the seals to atmosphere, thus providing a visual indication of hydraulic seal leakage. Used where contamination of the air motor from the hydraulic fluid being pumped is objectionable.
B Models: The "B" models have a bottom inlet connection for convenient tank top installation or alternate mounting configuration.
H Models: The "H" Models utilize special packing in the hydraulic assembly for maximum performance where hydraulic fluid media is contaminated with foreign matter, thus providing for a much greater life expectancy from the hydraulic seals than with standard o-ring seals. The "A" modification is included on all "H" models and the check valves have PTFE o-rings.
K Models: This models utilize a special air piston in the air motor assembly which decreases the stroke of the pump, thus minimizing the internal forces and increasing air motor life. Used in applications exhibiting rapid pressure losses, such as burst testing.
R Models: The "R" Models are furnished with an isolator attachment which prevents the hydraulic piston retracting into the air motor during operation, thus providing for 100% non-contamination of the hydraulic assembly from the air motor. The isolator also acts as a heat barrier.
