Techni Waterjet’s dual-unit Quantum ESP electric servo pump is designed for use with both the Quantum ESP55 and Quantum ESP66. The “D” dual unit increases cutting speed and optimizes performance by producing double the output volume of the “S” single models. The dual pump enables the waterjet to cut with a single, large cutting head or two standard cutting heads, depending on the application. It is synchronized to reduce pressure pulses and eliminate dead head spikes. This results in smoother cutting and increased high-pressure component life, the company says.
The pump’s servo motor directly envelops a high-load, precision ballscrew. The ballscrew directly houses the ceramic plungers, which reciprocate back and forth to create the pumping action in much the same way as a hydraulic cylinder works on an intensifier pump.
The infinite control of the servo motor and precision of the ballscrew enable accurate control over the output pressure and volume of the water displaced, the company says. This control enables operators to program virtually any pressure and flow rate, from zero to full capacity, while using only the power displaced at the cutting head.
