| Wildens Solenoid pump
technology uses electrical impulses to stroke the pump. The air valve is a two position,
four-way electrical solenoid valve that has a single operator and spring return. When
electric power is applied, the valve spool shifts to allow an air chamber to be
pressurized with air. When the electric signal is removed, the spring return mechanism
shifts the valve spool to a position where the pressurized air chamber is exhausted while
the opposite air chamber is pressurized. By alternately applying and removing electrical
power, the pump reciprocates much like a standard Wilden pump. The faster the electrical
impulses are provided to the pump, the faster the pump operates. The Solenoid Pump Controller I (SPC I) is designed to provide an
intuitive interface between you and your solenoid pump. In simplest terms, this device
energizes and de-energizes the solenoid coil at a programmed rate to control Wilden
solenoid-operated pumps. The pump speed can easily be adjusted by simply pushing the
appropriate (increase or decrease) buttons on the keypad. To expedite your pump speed
selection, three programmable "presets" are provided.
The LCD screen and LEDs (light emitting diodes) keep
you informed. These indicators display operational status, which allows you to operate the
pump from a remote location. The preset number, the stroke interval in seconds (pump
speed), the stroke counter, and stroke totalizer, are indicated on the LCD screen. The
leak detection LED informs you of the optional Wil-Gard leak detection device status. The
SPC I will stop pump operation if a leak is detected by the Wil-Gard diaphragm monitoring
system.
An external input can be utilized to remotely start and stop
the pump to customize the application. Liquid level controllers, proximity switches,
temperature switches, etc. can easily interface with the SPC I by simply wiring the
external component to the terminal strip and selecting the external input mode (Preset E)
on the SPC I. |
| Wilden solenoid-operated, double-diaphragm pumps are the
cost-effective choice of engineers, industry professionals, and maintenance personnel.
This pump technology utilizes compressed air as a driving force to displace process fluid
while electric signals control pump speed. Their inherent characteristics allow them to
excel in difficult pumping applications where other pump types fail.
