Products & applications Pumps Pump helps biogas scheme save €60,000


A Landia chopper pump is helping a community- owned district heating scheme save around €60,000 pa.


The long-shaft Landia pump has been handling heavy duty mixed waste, including slurries and fats for an anaerobic digester biogas plant operated by Beoffs in County Kilkenny, Ireland. Renewable energy generated by the plant serves local residents and a village hall in the area, but its primary beneficiary is the nearby school run by a charita- ble trust.


The chopper pump handles sewage sludge, food waste and various greases, as well as dairy slurry from three local farms,


Hygiene with a capital ‘H’


and has been in operation for over four years. Consultation and installation was carried out in conjunction with Drilling & Pumping Supplies (DPS) of Newtownards, with whom Landia have worked on several successful projects in Ireland. Jimmy Chadwick, plant man- ager at Beoffs, said: “This is hardly the easiest process for a pump, but the Landia unit has


proved extremely reliable and effective, despite every- thing we’ve thrown at it. Landia have also been very practical with their help in ensuring that this important part of our biogas process works properly. They always give us great back up.” Chadwick explained that this local community district heating system also provides valuable digestate/fertilizer to those farmers who have first provided the dairy slurry for the DAFF-approved AD plant. The Beoffs plant also benefits from income generated by a gate fee for the waste it takes in. Landia T: 01948 661200

With the availability of its ‘H’ series of sanitary pumps, Flotronic Pumps can supply sanitary pumps to companies insisting on 3-A authorised equipment. Displaying the 3-A symbol signifies


that processing equipment meets cer- tain material, design and manufactur- ing standards. “While 3-A is not a statutory requirement, it is a standard increasingly required by the sanitary industry,


particularly in the United


States,” said Flotronic’s Managing Director, Jane Waite. “Being authorised to display the 3-A symbol ensures credibility of the new ‘H’ series, at home and abroad.”


In line with the 3-A standard, the pumps have been designed so they can be thoroughly cleaned. The pump also features the Flotronic easy-mainte- nance, one-nut design, which means the pump can be maintained in min- utes. Cleaning is made easier by a spe- cially designed support stand which allows full rotation for draining. Flotronic Pumps T: 01444 881860

SPX metering pumps are gener- ally driven by an induction motor, enabling them to deliver an accurate and continuous flow rate. However, there are many applications in food processing which do not require a continu- ous flowrate, so it is necessary to keep starting and stopping the motor. This can lead to overheating, and it is also difficult to start and stop the motor accurately in order to precisely time its operation with other equip- ment. Combining the digital motor and drive with the meter- ing pump overcomes


Digital meters are the way forward these challenges.


Digital motors offer many advantages over standard induc- tion motors, and are designed to cope with frequent starts and stops. They provide relatively high torque in a compact size and can be run very slowly for extended periods, whilst the inclusion of a posi- tion encoder enables their speed and posi- tion to be accurately relayed to the control system. The flexibil- ity means they are able to drive to exact set positions. SPX

Flojet has announced the intro- duction of the Flojet LF Plus Beverage Dispense pumps line, a series of low flow industrial motor driven diaphragm pumps. The pump is one of the units in the Flojet LF Plus series. All of the pumps in this range are designed to reduce diaphragm cleaning time by up to 40% and weigh just 20 ounces. Flojet is a Xylem brand.


Using reciprocating diaphragm technology, Flojet LF Plus pumps are suitable for moving liquids in a range of temperatures, from 0- 43˚C and even those with acidic content, such as syrups, juice con-


centrates, teas, wines, draft beers and liquor. The pumps come with a 1.0 GPM (3.8 LPM) flow rate to deliver a virtually silent operation and can be used in applications where space is tight.


The pumps draw so little Turn losses into gains


With the objective of creating more energy-efficient pumps, M Pumps S.R.L has announced what its calls a ‘signifi- cant breakthrough’ in the development of it range of sealless, magnetic-drive pumps.

Pumps’ magnetically driven, sealless pumps offer leak-free, low-maintenance and reliable pumping, especially when the process involves aggressive, corro- sive fluids. However, one inherent dis- advantage of magnetically driven pumps is eddy current losses in the contain- ment shell, an inevitability when the shell is made from metal. The common solution to overcoming the effects of these losses is for pump motors to be ‘oversized’, but this results in increased energy consumption. Several approach- es have been made to address eddy cur- rent loses, with mixed results. However, M Pumps has now produced a hybrid rear shell design based upon an inner shell made from Hastelloy C and an outer shell which consists of a car- bon filament which is wrapped around the steel outer shell. The result is a composite rear shell construction with the properties of a non-metallic materi- al, combining the all-important qualities of optimum mechanical and chemical resistance. Pump trials have proven resistance to temperatures above 300°C, pressure resistance up to 500 bar and a reduction in eddy current loss- es by up to 90%. Pump Engineering T: 01903 730900

power that they can operate on battery power, allowing them to be mounted or used nearly any- where, or for back-up use during a power outrage.


Each pump features 360° quick connect swivel ports to allow for freedom of port orientation, flexi- ble mounting feet, an inline fuse, and a manual on/off switch that saves time and reduces operating costs. They can attain operating pressures of up to 40psi (2.75 bar), have self-priming capabili- ties up to six feet (1.8m), and dependable run dry capabilities. Xylem
