Stenner’s adjustable variable speed pump has a DC motor with a detachable pump head which is universal to all Stenner pumps. The SVP1 pump has a simple four button keypad with a large LED display. The pump is manually adjusted in 1% increments with the up and down arrows on the keypad. The SVP1 also includes prime and on/off buttons on the keypad. All Stenner metering pumps have a 3-point roller design in the pump head, which acts as a check valve to prevent back flow, siphoning, overdosing and loss of prime.
SVP variable speed pumps come optionally with 4-20mA input controls. SVP pumps operate in a 4-20 mA mode with an external port to accept an input control signa or can be overriden to be manually adjusted in 1% increments with the up and down arrows on the keypad.
