Grundfos DDI digital diaphragm dosing pump from 75 ml/h up to 150 l/h with real setting of the flow rate. The integrated high-performance microelectronics and the innovative speed-regulated drive technology produce a precise and continuous dosing guaranteeing consistent media mixing and process quality. The dosing rate is simply entered in liters per hour – and the pump takes care of the rest.

Digital Dosing
The use of stepper motor/EC drives optimizes control of the stroke speed and makes it extremely accurate. The duration of each pressure stroke varies according to the flow setting. The suction stroke time always remains constant but can be lengthened using the anti-cavitation function and thus adapted to the relevant needs. This way suction always takes place with the full stroke volume. This results in continuous dosing and lower pulsation in the dosing system – important factors in ensuring smooth pumping of outgassing media and in installations requiring longer suction lines.

Cost-effective dosing
DDI keeps energy costs at a record low, thanks to the advanced EC motor technology. Maximum efficiency is also ensured even by flows of 150 l/h

With a high accuracy of +/- 1.5 % repeatability throughout the adjustable range, DDI pumps reduce the consumption of chemicals by precisely dosing the required amoun

Grundfos Unilift KP submersible drainage pump are submersible drainage pumps for pumping drain water or grey wastewater. The KP is suitable for both temporary and permanent free-standing installation or installation in collecting tanks.

All Unilift KP pumps can be supplied with or without a level switch for automatic or manual operation. The strainer is clipped onto the pump housing and can easily be removed for cleaning and maintenance.

The robust design – all metal parts in contact with the pumped liquid are made of stainless steel – makes it ideal for rough environments. The outer casing is made in one piece. The motor is a canned motor with liquid-filled rotor chamber and water-lubricated bearings.

The motor incorporates automatic overload protection which cuts out the motor in the event of overload. When it has cooled to normal temperature the motor restarts automatically.

Applications
The Unilift KP pumps are designed for the pumping of:

Water from rivers and lakes
Rainwater, drainage water and water from flooding
Water for filling/emptying containers, ponds, tanks, etc.
Effluents from showers, washing machines and sinks below sewer level
Pool water
Ditch drainage water
Lowering groundwater
Domestic effluents from septic and sludge-treating systems
Effluents from viaducts, underpasses, etc.

Grundfos TPE3-TPE2 inline circulator pump provides unrivalled efficiency and a wide range of intelligent functionalities that makes it much more than a pump. TPE3 has a built-in heat energy meter as well as flow limiting functions eliminating the need for a pump throttling valve. With a wide range of intelligent control modes to choose from, the pump is easily commissioned to the system it is being a part of.

With a number of configurable relays and analog inputs, the complete TPE3 I/O package allows for better system monitoring and optimal pump regulation. It is supplied with wireless technology which enables it to connect with up to four single TPE3 pumps.

Connect and set-up any HVAC sensor to TPE3 and let the pump take charge of the system pressure and flow on basis of the ΔT and ΔP in the system. The intelligent TPE3 is a true plug-and-pump solution.

TPE2 is the ideal pump if you do not need the intelligent functions but instead want to connect all external sensors by yourself, if you want the pump to run at constant speed, or if you want an existing BMS system to control the pump.

Being part of the TP-family, TPE3 and TPE2 pumps are of the close-coupled type, i.e. pump and motor are separate units. Consequently, the pumps are less sensitive to impurities in the pumped liquid than similar pumps of the canned rotor type.

Applications
TPE3 and TPE2 are all-round In-line pumps that can be used in all heating, cooling and district energy systems. TPE3 and TPE2 make a significant difference in terms of comfort and system efficiency in several situations. Examples are:

One-String Heating Systems
Increase system efficiency and avoid penalties by a TPE3 that operates based on ΔT across the system to avoid increased return temperature.
Heat Recovery System
Reduce water temperatures and reduce costs: With a TPE2 pump you can add two temperature sensors and the pump will adapt the circulating flow in the system to what is really needed.
Boiler Shunt Pump
Boiler protection and reduced cost of operation: You can now use the TPE3 and an added temperature sensor instead of a normal pump running at full speed. The sensor ensures that the right temperature is maintained at all times.
Domestic Hot Water Recirculation
Gain control of hot water temperatures and save: Traditionally, a throttled constant speed pump runs 24/7 to ensure instant hot water, which is a waste of energy. A TPE3 can be applied and put in temperature control mode and the pump will maintain the desired

Grundfos DWK submersible pump is designed for dewatering and drainage applications. The cast-iron construction and the hydraulic design contribute durability and high efficiency. The differences between the DWK and DPK pump ranges lie in the discharge arrangement and the installation type.

The DWK is designed with a top discharge pipe and suction strainer, and is thus more suitable for temporary installation, whereas the DPK has a side discharge and a ring-stand or auto coupling (as accessories), and is suitable for permanent installations.

Applications
DWK/DPK are excellent pumps for dewatering and draining applications. The combination of compact design with high-pressure capability makes the pumps suitable for use in pits, whether for temporary or fixed installation. The installation design options provide the flexibility needed to cover many needs.

Applications include:
Construction sites
Excavations
Tunnels
Fish ponds
Drainage pits

Features and benefits
Durability
High efficiency
Installation flexibility
High-pressure capabilities, cost-effectiveness
