The Xylem Lowara DOC 3 submersible pumps range are suitable for both clean and dirty water. They are both corrosion-resistant and compact and utilise channel impellers for optimal life/performance. It can be supplied with/without a float switch and a built-in capacitor. The motor is cooled by the pumped liquid and thermal overload protection to protect the pump in case of overheating.
The main types are as follows:
DOC 3SG/A - Does not have a float switch and needs to be turned off/on manually, care must be taken to not allow the pump to run dry.
DOC 3/A - This version is automatic and uses to float to start/stop.
DOC 3/A GW - This is similar to the 3/A above but it has a vertical tube float for use in more confined spaces.
DOC 3/GT - This model is discontinued and replaced by the DOC 3/A GW.
Doc pumps are available with two different cable lengths, we have chosen to only supply the version with the 10m cable as it allows more practicality in real-world use. The shorter cable version is available on request but the price difference is negligible.
