Pump controllers monitor flow and/or level variables and control a pump accordingly to maintain the desired levels. Pump control can include simply turning a pump on and off or more advanced controls for pump speed, output pressure, etc. Installation is easy. The pump control panel is factory wired to provide flexible control and protect against short circuits and overloads. Ample space is provided for field modifications and installation of accessories. Siemens offers the NEMA Slim Line Class 82, Full Voltage Type Class 87, Reduced-Voltage Type Class 88 and Vacuum Starter Type Class 87.
NEMA Slim Line Pump Panel, Class 82
Siemens introduces its new Class 82 NEMA Slim Line Pump Panel. This newest addition to the already extensive line of Siemens pump panels was designed specifically for the agricultural market. It is well suited for irrigation and similar pumping applications and is built to withstand the harsh elements of the outdoors. Click Here for More Information
Full Voltage Starter, Class 87
The full voltage starter pump controllers are specifically designed for the agricultural, petrochemical and other industries requiring pump control. They are built to withstand the harsh elements of the outdoors and are well suited for the most demanding environments.
Typical Applications Include
Waste water treatment
Reduced Voltage Starter, Class 88
The reduced voltage starter pump controllers are designed for the same applications and environments the Class 87 full voltage starter pump controllers serve. However, these controllers provide added protection for your equipment by stepping up the motor speed and thus reducing starting torque. The reduced voltage starter pump also complies with electrical current restrictions of utility companies.
Siemens manufacturers three most used reduced voltage pump controllers:
Vacuum Starter Type, Class 87
The vacuum starter pump controllers are designed for the harshest environments. Typically environments include chemical, petrochemical, waste water treatment and mining. Contaminations present in these severe environments are detrimental to conventional air-break contacts decreasing their life expectancy and reliability. The Siemens vacuum starter pump controllers are well suited for these environments because the contacts are contained in hermetically sealed contact tubes. This prevents contaminates in the atmosphere from affecting the operation of the contacts. Additionally, neither arcs nor arcing gases are produced which dramatically increases the electrical endurance of the contacts.
