23.100.10 - Pumps and motors

This document specifies methods for determining the performance and efficiency of hydraulic fluid power positive displacement pumps, motors and integral transmissions. It applies to components having continuously rotating shafts. This document specifies the requirements for test installations, test procedures under steady-state conditions and the presentation of test results.

This document gives guidelines for:
a) presenting data on hydro-abrasive erosion rates on several combinations of water quality, operating conditions, component materials, and component properties collected from a variety of hydro sites;
b) developing guidelines for the methods of minimizing hydro-abrasive erosion by modifications to hydraulic design for clean water. These guidelines do not include details such as hydraulic profile shapes which are determined by the hydraulic design experts fo...view more

This part of ISO 10767 establishes a test procedure for measuring the source flow ripple and source
impedance of positive-displacement hydraulic pumps. It is applicable to all types of positivedisplacement
pumps operating under steady-state conditions, irrespective of size, provided that the
pumping frequency is in the range from 50 Hz to 400Hz.
Source flow ripple causes fluid borne vibration (pressure ripple) and then airborne noise from
hydraulic systems. This procedure covers a frequency...view more

ISO 8426:2008 specifies the methods of determining the derived capacity of hydraulic fluid power positive displacement pumps and motors under steady-state conditions and at defined, continuous shaft rotational frequencies. Units can be tested as a positive displacement pump, with mechanical energy applied to the shaft and hydraulic energy obtained at the outlet fluid connection, or as a motor, with hydraulic energy supplied to the inlet fluid connection and mechanical energy obtained at the shaf...view more

ISO 17599:2003 specifies methods for determining the steady-state performance characteristics and dynamic performance characteristics of positive-displacement electrically and electronically controlled hydraulic pumps, so as to allow comparison of the performance of different components.
Pumps covered by ISO 17599:2003 have the capacity to affect changes in the output flow or pressure in proportion to the electrical or electronic input signals. These pumps can be of the load-sensing control typ...view more

ISO 16902-1:2003 establishes a test code based on ISO 9614-1 and ISO 9614-2 for determining the sound power levels of a hydraulic fluid power pump under controlled conditions of installation and operation. The sound power level will include sound power radiated by any piping within the measurement surface. ISO 16902-1:2003 is suitable for providing a basis for comparing the airborne noise levels of any type of pump that is normally used to convert rotary mechanical power to hydraulic fluid power...view more

Provides a basis for the formulation of guarantees applied to cavitation pitting for reaction hydraulic turbines, storage pumps and pump-turbines. It addresses the measurement and evaluation of the amount of cavitation pitting on certain specified machine components for given conditions, which are defined in the contract by output, specific hydraulic energy (E), speed, material, operation, etc. The cavitation-pitting evaluation is based on the loss of material during a given time and under accur...view more

This part of ISO 3019 specifies sizes and dimensions and establishes an identification code for the two- and fourbolt
mounting flanges and the shaft ends of positive-displacement, rotary hydraulic fluid power pumps and motors.
It is applicable to cylindrical keyed shaft ends with an external thread, as well as to those without a thread, to
conical keyed shaft ends with an external thread and to 30° involute spline shaft ends.
NOTE Involute spline is in accordance with SAE J744 [1].

This part of ISO 4392 describes a method of determining the low speed characteristics of positive displacement rotary fluid power motors, of either fixed or variable displacement types. The method involves testing at slow speeds which may generate frequencies having a significant influence upon the steady continuous torque output of the motor and affect the system to which the motor would be connected.

This part of ISO 4392 specifies two test methods for determining the startability of rotary hydraulic motors. It describes two comparable methods of measurement, namely the constant torque method and the constant pressure method. Since the results obtained by these two methods are equivalent, no preference is given to either.
