Drainage pumps for the demanding needs of industry and rescue services

Choosing the right drainage pump is based primarily on the amount of liquid to be transferred, the required head and the quality of the liquid. In professional use, the pump’s ability to handle particles and impurities without the risk of clogging is especially important. The material choice, such as cast iron or stainless steel, determines durability in chemically demanding environments.

When sizing the pump, the requirements of the installation site must also be considered, such as the size of the pump pit and the available electrical connection. Large volumes of water in industrial applications require the raw power of solutions such as the Caprari DR series, while confined spaces call for the compact level switch technology of the Comex Drain range. In rescue services and emergency situations in property maintenance, the lightweight design of Mast Pumpen units and their ability to remove water almost completely from floor surfaces are key advantages.

BPI-Chempump supplies drainage pumps and the necessary accessories quickly, directly from stock. Satisfied customers include rescue departments and other authorities, as well as property maintenance companies and HVAC companies.

Our experts provide guidance in selecting the right equipment type and ensuring the correct capacity. Decades of experience in the field ensure expert support for questions related to both small submersible pumps and large industrial drainage pumps.

The German Mast Pumpen K series drainage pumps are lightweight, durable and versatile professional pumps for removing water from basements, wells and flood situations. They are suitable for pumping both clean and dirty water down to a level of 3 mm and can tolerate impurities up to 10 mm in size. The pumps can normally handle water up to +45 °C and, for short periods, up to +80 °C for a maximum of 3 minutes. Overload protection ensures safe operation.

The range includes several sizes for different flow and head requirements. The pump sizes are shown in the QH curve of the pump range in Figure 1, showing the flow rates and heads of the models. Figure 2 presents other technical data for this drainage pump range.

Drainage pumps are critical tools in situations where water or another liquid must be removed quickly. The equipment is designed to manage large volumes of water in different environments.

• Flood situations: Sudden floods caused by nature require immediate water removal to minimize damage and restore areas to normal use.
• Construction sites: Groundwater or rainwater accumulating during excavation is removed with drainage pumps to keep the site dry and ensure safe working conditions.
• Basements and parking garages: Water accumulating in basement spaces located in low-lying areas is removed efficiently to protect structures and stored items.
• Emptying pools and tanks: Regular cleaning of pools and tanks requires quick water removal to make maintenance work easier.
• Agriculture and rescue services: On farms, water areas are managed to ensure optimal growing conditions for crops, while rescue authorities use pumps to manage emergency situations.

Drainage pumps are needed for both small everyday water removal tasks and the management of major incidents.

A drainage pump is a submersible pump designed for removing liquid. The device is suitable for fast water transfer and control in property maintenance, industry, rescue service applications and emergency situations.

Choosing the right drainage pump is based primarily on the required flow rate and head, as well as the size of the impurities contained in the liquid being pumped. The chemical composition and temperature of the liquid, as well as the technical requirements of the installation site, are also taken into account when sizing the pump.

Most pump models require liquid to cool the motor. Devices equipped with overload protection help prevent damage in possible overheating situations. Correct installation and the use of a level switch ensure that the pump stops automatically before the liquid level drops too low.

Stainless steel is the best choice for corrosion resistance in chemically demanding environments. Cast iron offers exceptional mechanical durability and strength in demanding industrial or construction site conditions. The material choice determines durability in chemically demanding environments.

Professional-grade drainage pumps typically tolerate particles or other impurities up to 10 millimeters in size when the strainer is in place. Industrial pumps designed for handling larger volumes of water can process even larger impurities without clogging.

Automatic control is carried out with a level switch, also known as a float switch. The device starts and stops the pump according to the liquid level. In narrow pump pits, separate vertically moving AGMA or MOUSE level switches can be used.

Comex Drain models are designed for applications where a traditional floating switch does not have enough space to operate. The level switch uses a lift-style design that moves next to the pump.

The typical maximum temperature for continuous use is +45 degrees. Mast Pumpen K series units allow the pumping of water up to +80 degrees for short periods, maximum 3 minutes.

The range includes discharge hoses, fastening ropes and special rescue packages for quick emergency management. In addition to the pump, the rescue package includes the necessary connectors and hoses, as well as a storage box to make transport and storage easier. Models with level switches are also available.

The device is submerged directly into the liquid to be removed. The pump can be equipped with an automatic level switch for unattended operation. Comex Drain pumps are supplied with a 10-meter power cable and plug, with IP68 protection.
