Product Selection


Product & System Arrangement Considerations

Whether it’s a small bearing replacement on a roller in a steel mill or a replacement of a bearing on a bridge cap, Hydraulic Technologies offers various product solutions to meet a wide array of demanding MRO applications. Utilize this section to navigate through the selection process:
applicaiton overview

STEP 1: 

Application Overview - determine the type of lift or positioning equipment required for your application.

Things to consider:

  • Single or multi-point lift?
  • Balance or unbalanced load?
  • Guided or unguided load?
  • Synchronized or unsynchronized positioning?
Function

STEP 2:

What function is required? Understanding the application movement will determine the type of pumps and tools are required.

System Arrangements

Key points to review

Key Points to Properly Sizing Hydraulic System

Questions to be considered:

  • Total system load
  • Application loading conditions
  • Operating intervals
  • Movement velocity requirements
  • Environmental conditions
  • Mounting requirements
  • Pump configuration (manual or powered)
  • Cylinder Movement (single or double acting)
  • Return type (spring return, load return, or hydraulic return)
  • Cylinder type (center hole, low height, or locking collar)
  • Control options
  • Automation needs (manual controlled or PLC controlled)
  • System component hardware required
Cylinder selection

Cylinder Selection

Cylinder or Tool Type Consideration:

  • Type of cylinder: Single or Double Acting
  • Design Type: Spring Return, Load Return, Hydraulic Return
  • Cylinder Design: Center Hole, Low Profile, or Flat Jack
  • Material Type: Steel or Aluminum
  • Footprint Requirement
  • Lift Extension Needed
  • Piston Saddle Type: Flat or Swivel Load Cap
  • Handling requirements
  • Tonnage Requirements

Pump Selection

Pump Selection

Power Pump Considerations:

  • What is the preferred source of power? Manual (hand or foot-operated) provides portability and can be used where electricity or shop air is unavailable. Air/Hydraulic: Uses shop air or a portable air ­compressor. Electric/Hydraulic: What voltage is available? Is a ­battery operated pump preferred?
  • What maximum system operating pressure (psi) is required?
  • Power or pressure control switching
    What volume of oil delivery is required? (For manual pumps, cu. in. of oil per handle stroke.  For powered pumps, cu. in./min. of oil).
  • Is a single-speed or two-speed pump required? (Two-speed pumps deliver high oil volume at low pressure for rapid cylinder piston advance and then shift to a high-pressure, low-volume stage under load.)
  • Valve Control Requirements (2/3/4 Way, Manual or Solenoid)

Accessories Selection

Accessories Selection

  • Hose Type (Material, lengths and ID Size should be determined)
  • Manifold Requirements (what controls are required for load control)
  • Fittings required?
  • Couplers required?
  • Gauges (Analog and digital are available)
  • In-line Valve / Flow Control Requirements (Meters flow)
  • Do you need remote valves? (Will the valve be used with single or double-acting cylinders?)
  • Will the valve be mounted on the pump, away from the pump or directly into the hydraulic lines?
  • Will the valve be manually operated, or is a remote control preferred? 
    Is independent control of multiple cylinders or hydraulic tools preferred?
