WSPD Series – NEMA 4, with WSiQ

The WorldStart Positive Displacement (PD) control package is built for the demanding pumping applications, such as in oil & gas fields, salt water disposal, tough irrigation duties or controlling jet pumps.

Ultimate Control – The control panel, “At Speed/Run Bypass” and pilot devices are door-mounted for ease of access, and all operational parameters can be configured using the intuitive, built-in keypad.
Multiple Unit Programming – All parameters can be transferred to a USB memory storage drive for uploading to, and quickly configuring other units.
Reduced Heat Design – The “At Speed/Run bypass” takes over motor load control at full speed, which helps reduce panel heat.
Compact Footprint – Other components, such as terminal blocks, main circuit breaker are positioned for ease of service within a compact design.
Packed Solutions – All WorldStart PD packages are UL compliant, assembled, tested, and readied for operation prior to shipment.
