How It Works
Stenner's adjustable variable speed pump has a DC motor with a detachable pump
head which is universal to all Stenner pumps. The SVP4 operates in a 4-20 mA mode with an external port to accept an input control signal. The Stenner SVP4
pump has a simple four button keypad with a large LED display. The Stenner pump can override the 4-20mA mode to be manually adjusted in 1% increments with the
up and down arrows on the keypad. The Stenner SVP4 variable speed pump 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. This pump is also available without the
4-20 mA option at a reduced price. Contact us today to discuss the best model for your application.
The rotation of the shaft drives the roller assembly within the pump head. The chemical solution in the Stenner pump tube is captured
between the rollers as they rotate and compress the tube. As the rollers advance, the squeezed tube section regains its original form and
generates a vacuum, creating the self-priming feature that delivers a constant flow unaffected by the outlet pressure.
