Underpitch heating ensures perfect growth for soccer pitches Grundfos pumps have been installed on a range of under pitch heating systems for a number of soccer clubs in the UK. The pumps play an important role in ensuring that optimum growing conditions are maintained throughout the year, even during periods of extreme cold. Pumping systems for football grounds have extremely unusual requirements. As the pitch is effectively a living product, great care has to be take to ensure that optimum growing conditions are maintained, using specially built control systems from heating and pipework engineers, Arthur Pollard Ltd, to guard against over or under heating the pitch.
To eliminate problems caused by the use of low grade water as the heating medium, each under pitch heating system contains a sophisticated mixing and deaeration chamber. These use Grundfos UMC multi-speed pumps to circulate boiler water through the mixing chambers at approximately 82”C, while Grundfos LPlOO inline pumps provide the distribution to the pitch coils. The UMC multi-speed pumps save energy due to the use of unique three speed motors which can be changed manually or automatically when controlled remotely. The LPlOO single store inline pumps provide high levels of reliability and are designed to operate for long periods of time without routine maintenance. These are manufactured with stainless steel impellers and pump shafts, making them corrosion resistant. An injection system blends the returned pitch water with the boiler

“you name it, we’// manufacture it”
water from the mixing chamber to provide the required temperature through the pitch coils. Typically, 80% of the pitch water bypasses the injection system. It is not possible to treat the water for frost protection. Any leakages under the pitch would put chemicals into the soil, which could possible result in damage to the grass. Each of the football grounds contain approximately 39 000 metres of 20 mm plastic pipework, installed in over 200 independent circuits, fed from header manifolds. The under pitch heating systems have been designed to enable groundsmen to heat specific areas of the pitch that are shaded from the sun. This problem is aggravated by the installation of high sided spectator stands which leave large areas of the pitch permanently shaded and can have an adverse affect on the growth of the grass and the condition of the soil. To overcome this, the control system can be operated on a zonal basis to produce balanced growing conditions across the pitch, additionally, the system monitors temperatures at different points across the pitch to protect against ground and system frost. In ensuring that optimum growing conditions are maintained throughout the year, the under-pitch heating system, enables these clubs to have access to a high quality pitch at all times even in extremes of cold weather, when hard ground conditions could cause match cancellations.

Progressing cavity pumps supply mineral water Natural mineral water at town Buxton in Derbyshire, is being pumped from spring source to St Ann’s
spa UK the Well
A approximately 250 feet away by an ‘M’ Range Mono pump. Natural mineral water emerges from a rock fissure at a constant temperature of 27.5 “C and is then pumped at 7.5 l/min under a busy road up to St Ann’s Well, a local tourist attraction where the waters are taken up by the public. An even output pressure and non-pulsating flow are features of the ‘M’ Range which particularly impressed the operators, environmental health officers at Borough of High Peak. A steady flow of water at the Well is necessary to prevent splashing onto the pavement - a particular problem in winter when this water freezes. The mineral water’s relatively high level of manganese 19 mg/l - presents the pump’s operators with specific problems. Manganese build-up can quickly block pipes if they are not monitored and cleaned at regular intervals. The simplicity of the ‘M’ Range’s design however, means no special tools are required.

Portable unit cuts backup pumping costs
Ingersoll-Rand’s V4 portable pump is being used for overpumping pumping stations in Scunthorpe, UK
The V4 pump has many advantages over the traditional skid-mounted units which can prove cumbersome and are difficult to shift once on site. The standard format of all other pumps of this type is skid or site trolley mounted, ie. they are
transportable but not portable. Normally an add-on kit is supplied for portable applications, but inevitably this creates a unit with a high centre of gravity, where a wide wheel base is required to compensate. Ingersoll-Rand, however, has devel-

Scunthorpe Borough Council, UK, has purchased an Ingersoll-Rand V4 portable pump for overpumping applications at pumping stations in the Borough. The Borough Council maintains these pumping stations as agent to the Severn Trent Water Company and the new V4 pump will permit fast response overpumping in the event of fixed pump breakdown. In the past, overpumping applications have been carried out by hiring in large tankers, each costing approximately f400 per day in rental charges. The V4 pump will help the Borough Council to keep down operational costs and is effectively an environmental safeguard.
