Product Description
Features:The Double Float
® Master pump switch is a mechanically activated pump switch which provides automatic control of pumps in non-potable water and sewage applications.
The Double Float® Master pump switch consists of two mechanical floats and a splice tube. The splice tube contains a holding relay which enables the floats to function in series.
The holding relay eliminates pump chatter in turbulent conditions allowing the Double Float
® Master pump switch to operate relay control panels for larger pump applications.
The Double Float
® Master pump switch features:
• Encapsulated relay and splice provides reliable seal
• Controls pumps up to 15 FLA, 90 LRA, 120V or 240V
• Adjustable pumping range of 3 to 48 inches (7.6 to 122 cm) with increased pumping range up to 6 feet (1.8 m) available
• Floats are labeled for ease of installation
• Reliable, mechanical alternative for areas restricting the use of mercury
• CSA Certified; Three-year limited warranty
Specification:• Cable attached to float housing: flexible 18 gauge, 2 conductor (UL, CSA) SJOW, water-resistant (CPE)
• Cable above splice: flexible 14 gauge, 3 conductor (UL, CSA) SJTW, waterresistant, thermoplastic
• FLOATS: 2.74 inch diameter x 4.83 inch long (7.0 x 12.3 cm) high impact, corrosion resistant, PP housing for use in sewage and non-potable water up to 140
oF (60
