Product Description
Manual Control Pumps These low-cost metering pumps are ideal for general applications. They feature manual adjustment of stroke frequency and fixed stroke length via a digital keypad (360:1 turndown). For easy access, control modules are detachable. Remote Control Pumps Pumps feature digitally adjustable speed control and manual adjustable stroke length (1800:1 turndown). Input and output signals include external pulse input control, stop and pre-stop inputs, and stop and pulse outputs. Programmable Remote Control Pumps These programmable pumps allow you to program the pump speed and input settings using the alphanumeric display and four-button keypad. Control modules are detachable for easy access and remote capabilities. Pumps have digitally adjustable speed control and manual adjustable stroke length (1800:1 turndown). External input control is offered via a pulse input or analog signal. The analog signal is fully programmable. The digital mode allows you to multiply or divide external pulse by a factor of 1 to 999.
