The RainJet is a hydroejector designed to automatically clean tanks used for the temporary storage of stormwater or wastewater so that odour problems are avoided and storage capacity is maintained.
The RainJet continues flushing until the tank is completely empty and all the contents have been pumped into the sewer system. It uses the water already in the tank and hence does not need an external source of fresh water.
The RainJet is made either as a water/water (WW) or water/air (WA) ejector:
- RainJet WW with greater flow for cleaning wider tanks
- RainJet WA with jet that reaches further and is mixed with air.
The RainJet is made entirely of stainless steel of AISI 304/DIN1.4301 or AISI 316/DIN 1.4401, and is coupled to a wastewater pump of the SE or S type.
Applications
No matter what the size and layout, a customised solution of one or more RainJets can easily be designed to clean detention, equalisation or stormwater tanks used for the storage of excess water in order to minimise the risks of:
- Flooding or pollution of receiving waters if capacity of the sewer system is exceeded
- Damage of biological processes at the WWTP if untreated industrial process water arrives
- Disruption of purification processes at the WWTP due to hydraulic overload.
Features and benefits
- Available as water/water or water/air ejectors
- RainJet WA available with a 2nd stage for extra thrust
- Made completely in stainless steel for strength
- Available with standard pumps in many motor sizes
- Fitted with sturdy submersible wastewater pump of the SE or S type
- Suits tanks of different sizes, depths and shapes
- Mixing and cleaning handled by same the unit
- Large free passage – no clogging
- Fixed or auto-coupling connections suiting every type of installation
- Pumps on auto-coupling to make maintenance easier and more flexible.

Grundfos TP and TPE vertical in-line volute pumps are used in a variety of applications. The pumps are all single-stage, in-line centrifugal volute pumps with standard motors and mechanical shaft seals. The 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.
Two different models of vertical in-line volute pumps are available. Please note that there are a number of specific product variants available for each model. Detailed information on these variants can be found in Grundfos WebCAPS.
TP pump
This pump model is notable for its high levels of reliability and efficiency. Quiet, highly-efficient IE3 motors are standard components. All TP pumps are electro-coated to ensure high corrosion resistance.
TPE pump
The main difference between TP and TPE pumps is the motor. TPE motors have a built-in frequency converter, allowing different control methods to be employed. TPE pumps offer benefits with respect to energy savings and increased comfort.
Applications
These vertical in-line volute pumps are used in commercial buildings for air conditioning and heating applications.
The pumps are all single-stage, in-line centrifugal volute pumps with standard motors and mechanical shaft seals. The 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.
Features and benefits
- Optimised hydraulics for high efficiency
- Reduced power consumption

- Unlike end-suction pumps, in-line pumps allow the use of straight pipework, which often results in reductions in installation cost and amount of space occupied
- Hydraulically and mechanically balanced impeller (Series 300 and 400)
- The impeller is hydraulically and mechanically balanced to increase the life of motor bearings and shaft seals
- Pump housing and pump head/motor stool are electro-coated
- Improved corrosion resistance
- TPE, TPED – pumps with built-in frequency converter

DWK and DPK are submersible pumps 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.

Backwashing refers to the reverse-pumping of water, for example for the periodic washing of filters. Grundfos can supply pumping solutions that deliver the very strong force with well-executed flush times and speeds required for effective backwashing.
Backwashing is a form of preventive maintenance to prevent further clogging of the filter medium. Backwashing in water treatment plants is an automated process, usually run by programmable logic controllers (PLCs). The backwash cycle is usually triggered when the differential pressure over the filter exceeds a set value.
Grundfos can supply pumping solutions to cope with the hugely varying flow requirements for backwashing, ranging from huge split-case and mixed-flow pumps, where the focus is on moving water rather than added pressure, to our highly successful vertical multistage centrifugal pump (CR) – and covering all performance requirements in between.
Grundfos can supply the specialist expertise to help meet your performance objectives, from the initial identification of needs, to the selection, installation, operation, and maintenance of the pumping solution. Grundfos commissioning agreements ensure correct installation and service agreements cover all eventualities, from routine maintenance to spare parts and pump audits.

Grundfos’ new range of GHP (Grundfos Hygienic self-Priming) pumps takes efficiency and durability to new levels in sanitary processes.
The pumps are based on the well-known HILGE technology and are further optimised to offer reliable operation even under the tough conditions encountered in cleaning processes.
The single-stage self-priming GHP pumps combine the best of the F&B-HYGIA end-suction pumps with the reliable HILGE technology. The result is an optimised pump range that comes with increased efficiency compared to traditional side-channel pumps and can be counted on for long operational life.
One pump – More applications
Due to the robust construction of the new GHP pumps they are able to handle liquids with a high content of air as is the case in CIP return systems.
In effect, this means that the same pump can be used for product conveyance as well as for the cleaning processes. Compared to side-channel pumps, GHP pumps are also less sensitive to handling products containing particles.
Low noise operation
The GHP pumps feature a new, unique hydraulic technology that allows the impeller to be adjusted to accommodate exact duty-point requirements.
This translates into a noise level significantly lower than compared to traditional side-channel pumps.
Specially designed for sanitary applications
The all-stainless steel GHP pumps have been specially designed for trouble-free operation in sanitary processes such as:
- Cleaning processes (CIP return)
- Evacuation of tanks and pipes
- Pumping liquids with a high gas content
- Pumping liquids in Food and Beverage industries.
