In a bid to offer a solution to flood-prone areas and to solve issue of water-logging, Grundfos, a Danish pump manufacturer has offered robust dewatering solutions with its pumps and systems.

DPK and DWK, submersible dewatering, draining pumps, which can handle a particle size up to 15 mm and can be installed in the basements to manage the situation. They are an ideal solution as reliability and modularity are key elements required in critical situations. These pumps are highly useful in flood prone areas, construction sites and can also help to manage the critical situation.

These drainage or dewatering pumps are equipped with a semi-open or enclosed impeller with a robust cast iron construction to improve their durability. They are intended for submersible use in underground collection tanks in and around buildings for cost effective run-off management. They also have flexible installation options as they can be free-standing on a ring stand or be permanently installed on an auto-coupling system.

The DPK.V range of pumps are designed with a state-of-art super vortex impeller to transfer sewage to make run -off management efficient. DPK.V pumps have a particle handling capability of 65 mm or 80 mm, hence, they can be put into operation where there are coarse particles floating in the water. With the super vortex impeller, the design minimizes clogging. This makes DPK.V ideal to transport wastewater.

Meanwhile DWK pump range is primarily used for dewatering in construction sites. Their corrosion resistant components protect them from the harsh environments of a construction site. The primary differentiator between a DPK and DWK pump is in their discharge arrangement style. The discharge is placed on top and does not require any additional support to be placed. This will allow pumps to be put through the smallest manholes to displace water.

Some of the advantages of these pumps are such as built in bi-metal sensor to protect overheating; double mechanical seal positioned in the oil chamber to minimise downtime; easy to maintain oil plug in the seal chamber; hose or flange connection to be provided on the basis of requirements; wear and tear resistant impeller for an increased lifetime; and capabilities to manage high pressure and harsh environments.

These pumps have applications at construction sites, run-off management, excavations, tunnels and drainage pits. The durability, modularity and efficiency of these pumps make them the perfect dewatering and drainage solution at commercial establishments and construction sites.
