The right pump
Anyone in construction can tell you the value of having a top quality reliable pump on your site is critical. This can be for foundation drying and emptying plus Bentonite pumping for deep foundations, general over pumping services, general dewatering plus rewatering (rehydration) mains boosting, mains testing and mains cleaning Sewage by-pass and dust suppression.
Whatever the case reliability is paramount in a strict deadline situation.
Pumps are used for a variety of situations and this means that they come in various shapes and sizes from very large to very small each designed to accomplish specific tasks depending on the liquid or slurry to be conveyed, the rate or conveyance, height and rate. In order to wade through the wide range of available pumps it is critical to know what pump fits what job. The following companies focus on different types of pumps used in construction.

Peristaltic hose pumps
Flowrox pumps are applicable to a wide array of applications in the construction industry and are ideal for processes involving abrasive, corrosive, viscous or crystallizable media with high content of solids.
Flowrox peristaltic hose pump range includes three series of pumps that are ideal for transferring (LPP-T), dosing (LPP-D) and metering (LPP-M) duties. Flowrox hose pumps incorporate an advanced design; a single, bearing-mounted roller presses against the hose only once per the 360 degree operating cycle, producing the maximum flow per revolution which eliminates friction, maximizes hose life time and lowers energy consumption.
Construction industry applications include; grinding aid dosing, additives dosing, grout pumping and cement slurry transfer.
Grinding aid or alkanol amines and glycols have been utilized by cement customers for many years. There are now methods of delivery of grinding aids that have not previously been available. New peristaltic pumps are now available that provide process reliability and a lower cost of ownership of other pumps previously used in grinding aid delivery.
Peristaltic pumps have been in existence since the 1930s. Through the years, the designs have been continuously refined for improved performance and enhanced lifetime. During the early developmental years, the greatest peristaltic pump improvements have been advancements in rubber technology.
As rubber technology advanced, the need for replacements were seldom. Peristaltic pump technology has advanced similarly, but the quality and prevalence of rubber gets overlooked. If average consumers take the time to consider the reliable performance of their automobile tires, they may realize that rubber is a durable material that is used globally in millions of products that we rely on to make our lives easier and more efficient.
Maintenance of all peristaltic pumps is relatively simple. It consists of removing a broken or damaged hose, cleaning the interior casing of the pump of contaminants and then installing a new hose with the manufacturer’s required amount of glycerin. In some designs, this can be accomplished by one person in 15 to 20 minutes. In other designs, the maintenance may require two or three people, but it is still a fairly easy and uncomplicated procedure.
Also with peristaltic pumps, you do not need to remove the pump from the pipeline or take it to a repair shop. The repair work can be done at the pump installation location. With peristaltic pumps, the only required parts are a new hose and the necessary glycerin.
Today, the cement manufacturers understand the value of engineered-rubber technology. It is utilized in many locations in cement plants such as rolling mill liners, expansion joints, and abrasion-resistant rubber hoses and elbows. The heavy-duty lined peristaltic pumps utilize this same highly-engineered-rubber technology that will far outlast metal components subjected to the abrasive nature of pneumatically-conveyed cement.

Submersible wastewater pump
Increasing concerns about CO2 emissions and energy costs has led to greater focus on energy use worldwide. Grundfos is uniquely positioned to ensure a correct understanding of efficiencies and how these combine with hydraulic free passage and constructional robustness in state-of-the-art wastewater pumps.
Environmental issues have led to legislation that places new requirements on wastewater handling. Pumping wastewater through the connection network or around the treatment plant accounts already today for a substantial part of the energy bills faced by municipalities and water utilities. By choosing state-of-the-art wastewater pumps with the highest total efficiency, no compromise on hydraulic free passage and constructional robustness, you are well on the way to bringing down CO2 emissions and reducing operating costs for wastewater pump systems.
What matters to your energy bill is the total efficiency – meaning the total wire-to-water efficiency. In a wastewater pump there will be electrical, mechanical, and hydraulic losses. A pump manufacturer needs to master all of these without compromising reliability. Grundfos does precisely this and can therefore supply high efficiency products.
The IEC60034 standard sets minimum efficiency requirements for electrical motors, but is only valid for fan-cooled electrical norm motors. When Grundfos marks a submersible wastewater pump with, for example “IE3” efficiency, we will at all times be able to provide a type-test certificate for the motor components, tested in a norm motor execution according to the IEC60034 standard, which is your assurance of the validity and trustworthiness of what they communicate.
Pump efficiency is only interesting if reliability is not compromised. Pump maintenance is costly, whether planned or unplanned, and Grundfos does not compromise on reliability with their products. For constructional robustness with key components, Grundfos for example uses: Tapered roller bearings: Even though tapered roller bearings have higher losses compared to ordinary roller bearings, they have decided to keep these types of bearings to gain longer lifetime in heavy-duty operation.
Shaft seal: Grundfos pumps come with double mechanical shaft seals in a cartridge solution. This robust construction consumes additional energy, but ensures longer operational time and less downtime. Replacement is easily done in the field without use of special tools.
Traditionally there has been a trade-off between free passage in hydraulics for reduced clogging, and high efficiency. Grundfos has resolved this traditional compromise and is able to supply wastewater pump systems that offer superior hydraulic efficiency without compromising free passage. Soon we will be revealing how you get superior hydraulic efficiency without compromising free passage.
On 8 May 2012, Grundfos released a new and expanded range of wastewater products that will help you increase your total wire-to-water efficiency, which is central to keeping your CO2 emissions and costs down. Let Grundfos help you find the right pump for your specific application and optimise your business.
