IPH-22A-8-8-EL-11

Description: Double IP Pump

The IPH Series Double IP Pump, configured with the High-Pressure Low Noise IPH Series and IP Pump, greatly expands the range of application for the IP Pump. A wide selection of pump combinations provide options that are perfect for just about any type of application.

All of the types in the new design (11D) series are installation compatible with the previous design (10D). Note, however, that there is no longer compatibility for some of the seal components between the IPH-3 and IPH-4 sizes.

Notes:

  1. Maximum Pressure: Maximum pressure limit when there are frequent pressure changes. However, maximum pressure is the same as rated pressure when load is applied to the head side and shaft side simultaneously.
  2. Suction Pressure: -3 to +4 psi (-0.02 to 0.03 MPa {-0.2 to +0.3 kgf/cm2})
  3. Avoid installation with the suction port towards the bottom of the pump. If the revolution speed will exceed 1800mm-1, provide separate piping for shaft side and head size IN ports.
  4. Specify using the model number format shown in the Model Number Explanation image when pipe flange is required
  5. Working pressure is continuous operating pressure when the same pressure exists on the head side and shaft side.
  6. Individual pump performance on the head side and shaft side is the same as that of the single pumps. Required power is the sum of the power required by each of the two pumps

Handling:

  1. Handling is in accordance with procedures for the IPH pump. See IPH Pump Handling section or page C-1 in the Nachi Standard Hydraulic Equipment catalog for more information
  2. The "Required Power at 1200min-1, 21MPa (kW)" column in the Specifications image are based on combinations that provide the maximum capacity for each model number, when pressure at both the head side and shaft side is 3046 psi (21MPa). Examples of combinations that provide "the maximum capacity for each model number" are IPH-22B-8-8-11 for IPH-22B, and IPH-46B-32-125-11 for IPH-46B. A capacity of 125 for all *6B Type 6 pumps is used for calculations.
