Variable Speed Metering Pump SVP Series From Stenner

PERISTALTIC METERING PUMPS SINCE 1957

Variable Speed Metering Pump SVP Series

The SVP series is a variable speed metering pump with manual or automatic control.

The SVP Series is an adjustable variable speed metering pump with a DC motor and a detachable pump head. It features a rugged polycarbonate housing, heavy-duty gear motor and LED display with a four button control pad for easy operation.

The SVP is categorized into two sub-series, SVP1 and SVP4. The SVP1 is manually adjusted using the keypad. The SVP4 is designed to respond directly to a 4-20mA input signal from water treatment controls including pH and ORP monitors to maintain proper water chemistry and treatment of effluent discharge water. The SVP4 is equipped with an external port to accept the signal or it can override the 4-20 mode to be manually adjusted with the arrows on the keypad.

The SVP4’s ability to accept a 4-20mA signal to pace the pump makes it well suited for the industrial user and municipal water treatment and wastewater treatment plants. Municipalities that supply potable water to residential and commercial sites require treatment of the well or surface water source they use. The SVP can inject sodium hypochlorite or other related disinfectants or meter solutions to oxidize problem water such as excessive levels of iron, manganese, and hydrogen sulfide which can cause staining and rotten egg odor.

Other applications include:

• Treatment of return wastewater before it can be processed for further usage.

• Injection of liquid biocides in cooling towers for prevention of Legionnaires disease.

• Corrosion, scale, and algae control on plumbing fixtures and water supply equipment.

• Metering additives specific to a manufacturing process.

• pH control for process water or metal plating discharge water.

How It Works

The output is adjusted by a digital keypad to increase or decrease the motor speed. With a 20:1 turndown, the output control ranges from 5% to 100% in 1% increments for precise chemical injection and adjustment. The keypad has four buttons: prime, on/off and up and down arrows.

Unique Stenner Features

• Interchangeable pump heads and tubes to convert one model to another without having to purchase a new pump.

• Easy and fast tube replacement without tools with the QuickPro® pump head.

• The pump is built with two detachable components; the motor and pump head that can be separated without tools.

Sub-series

The same output range is available with the SVP1 (manual) or SVP4 (4-20mA). The output capability is different according to the pressure rating.

• 0.3 to 40.0 gpd at 100 psi ( 1.1 to 151.4 lpd at 6.9 bar)

• 0.3 to 85.0 gpd at 25 psi (1.1 to 321.8 lpd at 1.7 bar)

* Input Signal Voltage/Resistance Max. 48 VDC/128 ohm.

NOTE: Injection check valve included with pumps rated 26-100 psi (1.8-6.9 bar)

NOTICE: The information within this chart is solely intended for use as a guide. The output data is an approximation based on pumping water under a controlled testing environment. Many variables can affect the output of the pump. Stenner Pump Company recommends that all metering pumps undergo field calibration by means of analytical testing to confirm their outputs.
