Variable Speed Metering Pump - SVP4L2 w/ 4-20mA Series From Stenner

• 25 psi (1.7 bar)

• max 17 gpd (64 lpd)

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 SVP4 pump has a simple four button keypad with a large LED display. The pump can override the 4-20mA mode to be manually adjusted in 1% increments with the up and down arrows on the keypad. The SVP4 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.

The rotation of the shaft drives the roller assembly within the pump head. The chemical solution in the 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.

Advantages

• Self-priming up to 25 feet and does not lose prime

• Can pump off-gassing solutions

• Solutions contained in tube, not exposed to pump components or air

• Subassemblies fit together without tools; easy service or conversion to another model

• Pump head universal to all Stenner pumps

• Can run dry without damage

• Will not clog from dirt or debris

• Reproducible outputs within 2%

• Pump tubes accept a variety of chemicals

• Heavy duty motor for longer life and quiet operation

• 20:1 turndown in 1% increments, non-scalable

• Four-button keypad with large LED display

A rotating assembly of rollers compresses a flexible tube within a housing to create a vacuum to lift a chemical solution. The self-priming peristaltic pump is also referred to a hose, tube or dosing pump.
