KAZEL 3-Hole UNI Bi-Directional Gear Pump
Kazel 3-hole UNI bi-directional gear pump is used in truck hydraulics, for example on dump trucks and crane manipulators.

|---|---|---|---|---|
| UNI-3 017 | 17 cmcm³/revrev | 280 bar | 2300 rpm | 300 rpm |
| UNI-3 022 | 22 cmcm³/revrev | 260 bar | 2300 rpm | 300 rpm |
| UNI-3 034 | 34 cmcm³/revrev | 260 bar | 2300 rpm | 300 rpm |
| UNI-3 043 | 43 cmcm³/revrev | 250 bar | 1800 rpm | 300 rpm |
| UNI-3 061 | 61 cmcm³/revrev | 220 bar | 1800 rpm | 300 rpm |

- 01Its main advantages are directly related to its construction: a 3-hole mounting pattern, UNI-standard rear flange, and the ability to operate in both directions of rotation.
- 02Rotation versatility and simplified inventory
- 03Bi-directional operation: the pump can operate clockwise (CW) or counterclockwise (CCW). No internal modification or conversion is required.
- 04Inventory optimization: companies and service centers no longer need to purchase separate left- and right-rotation pumps. One model replaces two, saving costs.
- 05Universal compatibility: the pump easily fits the power take-off (PTO), regardless of the rotation direction of the truck gearbox shaft.
- 06Compact and standard mounting
- 07UNI 3-hole standard: the 3-bolt mount complies with traditional European standards, allowing the pump to be installed perfectly on old or new trucks without adapters.
- 08Direct connection: it mounts directly to the PTO, saving space and leaving free room for other chassis components.
- 09High durability and reliability
- 10Robust cast-iron body: Kazel manufactures these pumps from cast iron designed for heavy-duty conditions. They withstand high pressure, often up to 300 bar, protecting the system against sudden pressure spikes, such as when lifting a dump body.
- 11Operation at extreme temperatures: the pump operates stably from -40°C to +145°C, ensuring reliable performance in both severe winter and hot summer conditions.
- 12Simple hydraulic system
- 13Bi-directional ports (inlet/outlet): when the rotation direction changes, the oil-flow direction changes automatically as well. In some systems, this eliminates the need for additional complex directional valves.
- 14Protection against oil leakage: built-in special seals work effectively under load in both directions and prevent oil leakage under high pressure.
