How to Select the right pump
 1.Data for pump design
    The following parameters are required for designing and selecting pumps:

  1. Required operating pressure
  2. Desired pump capacity at operating pressure
  3. Available air drive pressure
  4. Medium
  5. Temperature of the medium
  6. Ambient Temperature

    Depending on the application, you may require additional data.For more detailed specification and performance data , please contact us directly by email or call.- we are happy to assist in the designing process.
2.Required operating pressure and pump capacity
Specifications of pump operating pressures are essentially based on an air drive pressure of PL = 10 bar (145 psi). The operating pressure (PB) can be determined by multiplying the pressure ratio of the pump(i) by the available air drive pressure (PL) PB= i × PL.

    3.Specifications of pump capacity at the respective outlet pressure can be found in the pump capacity tables following  Medium
The pump model should be selected to match the medium to be pumped, as it is the properties of this medium which determine the requirements for the sealing materials and the wetted parts.
LOYO  pumps are suitable for a large variety of media. Standard designs are available for oil and water and for many special media.
    4.Dimensions and weight
    Some applications require special pump dimensions and weights. Please refer to the tables and option lists for our pump series for more information about this as well as on the availability of the
Applications include:
• Pressure testing
• Work holding/power clamping
• Jacking/lifting
• Valve actuator control
• Hydraulic cylinder actuation
• Press safety overload devices
• Roller tensioning
• Metering
• Precision lubrication and spraying
• Liquefied gas transfer
