Hydraulic Torque Wrenches and Torque Tools Manufacturing

The Z-Class power pumps have incorporated the latest metallurgical, bearing and seal technologies to produce a pump whose features and benefits far surpass the electric pumps that are available today. By reducing the number of moving parts, improving flow dynamics and decreasing friction, Z-Class pumps will stay on the job longer, require less energy to operate and when needed, have lower service costs.


Z-Class Pumping Element

	Highly efficient design - provides increased flow rates, reduced heat generation and a decrease in power consumption. This means improved tool speed and increased service life – which results in higher productivity and lower operating costs.

	Heavy-duty bearings - extend pump life by reducing friction, reducing surface-loading and lowering bearing stresses.

	Pump cavity oil bath - extends pump life by reducing heat, improving lubrication and reducing wear.

	Self-priming, high flow 1st stage pump - increases pump performance by super charging the 2nd stage piston pump – improving oil flow in both hot and cold weather operation.

	Balanced rotating components reduce vibration - creating a smoother running pump – reducing wear, friction and sound levels.

	Replaceable piston check-valves - increases service life of major pump components.


ZU4 Electric Pumps

	Heavy-duty composite shroud - protects electric motor and key electrical components from environmental contamination, rain and debris and provides a non-conductive ergonomic handle for the operator.

	Low-voltage pendant - features sealed switches and operates at 15 vdc for improved operator safety.

	Easily accessible brush cavity - allows rapid brush replacement in the field.

	Brush design - lasts 4-times longer than current designs and features “auto-stop” shunt to prevent commutator damage from normal brush wear.

	Reduced current draw - extends brush life and reduces electrical load on electrical circuits and generators.
