The SVP Series from Stenner Pump Company is an adjustable, variable-speed peristaltic metering pump that can accept a 4-20mA signal to pace the pump, making it suitable for industrial applications and municipal water and wastewater treatment plants. It has a DC motor and an LED keypad to adjust the output by increasing or decreasing the motor speed. The turndown ratio is 20-to-1 with 1 percent increments. They offer a maximum of 40 gpd with pressures to 100 psi. 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 includes an external port to accept the signal, or it can override the 4-20 mode and be adjusted manually with the arrows on the keypad. 800/683-2378; www.stenner.com.
