Axual-piston-piston adjustable series pumps on ... 74m 90/32Sh are designed for general engines in the hydraulic drives, where adjustable supply is required with a constant direction of the flow of working fluid.
The pump is designed to convert the mechanical energy of rotation of the drive shaft into the hydraulic energy of the working fluid flow.
Pumps are made by right or left rotation (index L), with mounting on paws or flange (index f).
Types of regulators installed on the pump for ... 74m 90/32sh:
| Type of regulator (regulator index) | The purpose of the regulator |
| Manual (p) | Provides work on any presentation in the range from nominal to zero. Formation installation - manual. |
| Electromagnetic (m) | Provides work on any presentation in the range from nominal to zero. Submission installation - turning on the electromagnet, the inclusion sequence of each of 4 fixed feeds, arbitrary. |
| Following (c) | Provides work on any presentation in the range from nominal to zero. The supply is installed by the setting device (fist, copier, etc.) |
| Power regulator (d) | Provides work in constant power mode. Formation installation - automatic, depending on the working pressure. |
