Select the model that suits your application. For special requirements please refer to the custom build section below.
Adjustable Relief Valve
All VM and VE-Series have a user adjustable relief valve to allow the operator to easily set the optimum working pressure.
Locking Valves
For applications requiring positive load holding, VM-Series valves (except VM32) are available with a pilot-operated check valve. This provides hydraulic locking of the load until the valve is shifted into the retract position. Order this feature on your ZE-series pump by viewing the information in the “Custom Build Your ZE-Series Pump” tab below.
Single or Two-stage | Choose single-stage pumps for applications that require constant flow regardless of pressure such as testing or clamping.
Two-stage pumps have an increased output flow at low pressure to allow fast movement towards the load, for reduced cycle times and increased productivity.
Assisted Return Pumps
To improve productivity and plunger retraction, Kiloton offers valve configurations designed to accelerate your cylinder retraction speeds, ZU4 and ZE-Series pumps feature Venturi Valve Technology to facilitate the faster return of single-acting gravity and spring return cylinders.
