The Xylem Lowara DOC 3 submersible pump range is suitable for both clean and dirty water. This 'go-to' choice for domestic sumps is corrosion-resistant, compact and utilise channel impellers for optimal life/performance. It can be supplied with or without a float switch and in 110v or 230v formats. The motor is cooled by the pumped liquid and there is 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. Suits sumps approximately or larger than 400x400mm and 330mm deep.
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. Suits sumps down to 220x220mm and 160mm deep but are also suitable for larger locations.
DOC 3/GT - This model (107540250XXXUA) is discontinued and was replaced by the DOC 3/A GW. It is very similar and will work in the same applications.
Doc pumps are normally available with two different cable lengths but we have chosen to only supply the better 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 is higher!
