The pumps automatically reciprocate on a differential piston principle. A large piston driven by relatively low pressure drive acts directly upon a smaller hydraulic piston.

The nominal ratio between piston sizes is indicated in the model coding and approximates to the maximum working pressure. The actual ratio is about 15% above nominal so that the pump continues to cycle when drive pressure equals nominal ratio. Initially, the pump will cycle at maximum speed acting as a transfer pump to pressurize downstream.It will cycle at a slower rate as the fluid meets resistance until it stalls at maximum output pressure. When a pressure drop downstream occurs, it will recycle as necessary in an effort to maintain maximum pressure. Stall pressure is achieved when the outlet pressure rises and offers more resistance to the reciprocating differential piston assembly. The piston assembly then stalls when the forces balance, e.g.when drive pressure x drive piston area equals outlet (stall) pressure x driven hydraulic plunger area.

The pump design is sensitive to very small pressure drops due to the low frictional resistance of the large diameter drive piston and hydraulic piston seals.

泵根据差动活塞原理自动往复运动。由相对低压驱动的大活塞直接作用在较小的液压活塞上。

活塞尺寸之间的标称比率在编码的模型中表示，并且近似于Zui大工作压力。实际比率比额定值高大约15％，使得当驱动压力等于额定比时泵继续循环。Zui初，泵将以Zui大速度循环，用作输送泵以向下游加压。当流体遇到阻力时，泵将以较慢的速率循环，直到其在Zui大输出压力下失速。当下游出现压降时，其将根据需要再循环以努力保持Zui大压力。当出口压力升高时实现失速压力，并对往复式差动活塞组件提供更大的阻力。然后，当力平衡时，例如当驱动压力x驱动活塞面积等于出口（失速）压力x驱动液压柱塞面积时，活塞组件失速。

由于大直径驱动活塞和液压活塞密封件的低摩擦阻力，泵设计对非常小的压降敏感。
