European Union (EU) legislation is acting as the primary driver for the European water and wastewater market for pumps, even as demand from eastern Europe promises exciting new growth potential. Proactive operational efficiencies of municipal authorities and private water companies will overcome challenges related to investment flows, improper water distribution and treatment infrastructure, while supporting overall market expansion.

Suited for handling of ceramic slip, SPX Zero Shear Pump is extremely gentle, imparting virtually no shear, aeration, or agitation on pumped product. It is virtually maintenance-free with no seals to replace, no check valves to clog, and no rotors or stators to wear out. Pump is unaffected by abrasive products because pumped ceramic slip is contained within tubing at all times. With self-loading design, hose replacement is quick, minimizing downtime.

Traditional systems rely on centrifugal pumps to return the condensate, but the volume of condensate varies according the demands placed on the system. Given that frequent starting and stopping direct on-line motors seriously reduces their service life, large condensate recovery units (CRU) are therefore needed to collect the condensate until the stored volume is sufficient to start the pumpsets and run them at a fixed speed for a period of time that is governed by the maximum number of motor starts per hour. With a limitation of some 10 motor starts per hour, the result is that the condensate has often lost much of its sensible energy by the time it is returned to the system.

A new range of condensate recovery units (CRUs) saves energy by using variable speed technology. Switching pumps on and off more regularly returns hot water to the system before it can cool down – slashing the cost of re-heating.
The developer is Amarinth, a UK-based firm that specialises in the design and manufacture of centrifugal pumps and pumping systems for industrial, chemical and pharmaceutical applications.
For 18 months, Amarinth worked with one of its customers – steam heating specialist Spirax Sarco – on developing a new range of CRUs. The client wanted better performance and greater reliability than competing CRUs, but at a competitive price. Variable speed technology was also a ‘must-have’. The tanks were to be made from stainless steel, the footprint was to be smaller and the range of CRUs significantly rationalised.
The result – the ‘Ci-Nergy’ CRU, launched in January 2006 – should cut running costs of steam heating and process systems. The system’s speed control acts as a soft start system, enabling the pump to be stopped and started frequently. The accumulated condensate – and associated latent heat – are then returned to the system more rapidly than by traditional methods, using fixed speed pumps with float switches or controls. The returning condensate can be up to 10°C hotter, which could save re-heating costs of up to £10,000 per annum.
Reductions of up to 75% in electricity costs can be achieved by running the pump as slow as 10Hz. The savings are exponential (often referred to as the ‘cubed law’) and so by using variable speed technology, Ci-Nergy operates anywhere between 10 and 50Hz, to match the level of condensate arriving in the tank.
According to Oliver Brigginshaw, managing director at Amarinth: “This delivers typical electricity savings of a further £1,000 per year per unit.”
He adds that, in most cases, payback on the CRUs “is between six and nine months”.

For the first time in Iran, researchers at the Chemistry Department of Shahid Modhej (Zargan) Thermal Power Plant prototyped the first domestic centrifugal pump from the foreign ones.
According to the reports released on Monday, as these centrifugal pumps are being used in the water treatment installations of the power plants, and also with regards to the fact that the high prices of the relevant spare parts have created lots of problems, the Iranian researchers decided to offer Iranian pumps to the domestic markets.
The 200-23 and 250-29 pumps of Iran Pump Company are now being used instead of the British and South Korean pumps.
Zargan Power Plant is under the management of Mostazafan Foundation (MF).
This power plant produced some 2,020,794 megawatts electricity last year.

Crane Pumps and Systems, Inc. Barnes EcoTRAN™ Pressure Sewer System, a residential basin package for use in pressure sewer systems, preserves groundwater ecology by collecting and grinding residential sewage in an underground basin and transmitting the waste under pressure to a remote private or municipal waste treatment plant. Pressure sewer systems provide an economical sewering solution for waterfront, hilly, remote or otherwise challenging properties.
Barnes EcoTRAN Pressure Sewer System offers simple installation. The lower basin is ALWAYS the same and the riser pipe is easily adjusted to the desired depth on the day of installation. Pre-installed epoxy-coated rebar simplifies ballasting and regardless of the depth requires only 1/3 yard of concrete to set in place. Three inlet positions provide substantial piping location flexibility.
In addition to simple installation Barnes EcoTRAN Pressure Sewer System comes with a choice of two highly dependable centrifugal grinder pumps including silicon carbide mechanical seals and 100,000-hour bearings to minimize service calls. The unit is also provided with an automatic pressure switch to control pump operation that is immune to grease build.

In this time of escalating energy prices, new technologies that can reduce steam operating costs are high on most plant operators’ agendas. One area where significant savings can be generated is by improving the efficiency of condensate recovery. Oliver Brigginshaw explains.
Steam heating and process systems generally collect condensate and return it into the system to recover its sensible heat. Clearly the quicker the condensate can be returned the more sensible energy is recovered, thereby reducing operating costs.
Traditional systems rely on centrifugal pumps to return the condensate, but the volume of condensate varies according the demands placed on the system. Given that frequent starting and stopping direct on-line motors seriously reduces their service life, large condensate recovery units (CRU) are therefore needed to collect the condensate until the stored volume is sufficient to start the pumpsets and run them at a fixed speed for a period of time that is governed by the maximum number of motor starts per hour.

The PMP25 provides an efficient low cost solution to the prevention of damage to industrial electric pump motors caused by overload, jamming, loss of load, pump dry running or loss of prime.
The rugged polycarbonate sealed enclosure may be mounted in many configurations including on a door, wall or cabinet or inside the control enclosure. The unit is easy to install and displays true power (Volts x Amps x Power Factor) on a large easy to read bright red digital LED display. Display configurations include % full load, Horsepower or Kilowatts.
Both high and low power trip relays with adjustable start up delay and individual trip timers are standard features. The low power trip, when used to detect dry running, is up to ten times more sensitive than that of conventional undercurrent relays. The 4-20mA analogue output and individual trip relays allow the flexibility of pump motor control and performance monitoring via external instruments such as Computers, Chart Recorders or Data loggers. The high power trip is provided for the detection of problems such overloads, jammed impellers, bad bearings or blocked outlets and a low power trip provides detection of low load or no flow conditions such as cavitation or loss of prime.
