Optional Accessories
An optional piggy back single float switch can be supplied for applications requiring automatic operation. The package includes a 30 ft/50ft (9m/15m) power cord with piggy-back power plug, a variable length float tether, and a sealed float.
Pumping range is determined by tether length:
- Tether Length:
- 3.5 in. (89 mm)
- 5 in. (127 mm)
- 7 in. (178 mm)
- 9 in. (229 mm)
- 11 in. (279 mm)
- 13 in. (330 mm)
- 15 in. (381 mm)
- Corresponding Pumping Range:
- 6.5 in. (165 mm)
- 7.5 in. (191 mm)
- 8.5 in. (216 mm)
- 10 in. (254 mm)
- 11 in. (279 mm)
- 12.5 in. (318 mm)
- 13.5 in. (343 mm)
Pumping range is based on operation in non-turbulent conditions; actual range may vary due to temperature conditions and cord shape. Tether length increases variance of pumping range.
