Intelligent submersible pumps for flood control

April 11, 2020 10:43 am

Waterlogging during monsoons is a common occurrence, making many areas prone to floods. Due to the lack of efficient infrastructure, water gets accumulated and floods the low-lying localities. This disrupts livelihoods, leaving cities to come to a standstill. Commercial establishments are worst-hit by the downpour, as many of their basements get flooded and cannot be accessed until the situation gets back to normal. Dewatering pumps play a major role in run-off management.

Grundfos offers excellent and robust dewatering solutions with its pumps and systems. DPK and DWK are submersible dewatering, draining pumps by design. These pumps can handle a particle size up to 15 mm and can be installed in 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 and construction sites and can also help to manage critical situations.

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

The DPK.V range of pumps is designed with a stateof- the-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 minimises clogging. This makes DPK.V ideal to transport wastewater.

DWK pumps
This 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.

Features and benefits of DPK and DWK pumps
• Built-in bimetallic sensor that protects the pump from overheating
• Double mechanical seal positioned in the oil chamber to minimise downtime
• Easy maintenance of 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
• Capabilities to manage high-pressure and harsh environments

Applications
• Construction sites
• Run-off management
• Excavations
• Tunnels
• Drainage pits

The durability, modularity and efficiency of these pumps make them the perfect dewatering and drainage solution at commercial establishments and construction sites.
