High-Performance In-line Pumps for Skyscrapers

Since land prices are steadily rising, there is a continued trend in the building industry worldwide towards ever higher skyscrapers. As a consequence, the demand for high-performance circulating pumps for HVAC systems is on the increase, and the new Etaline-R in-line pump series of KSB is suited to meet this demand.

Thanks to its compact in-line design, this pump type requires significantly lesser expensive space than conventional long-coupled models.

The new Etaline-R type series comprises 14 pump sizes and its maximum motor rating is 315 kW. The pump series generates a maximum flow rate of 1,900 cubic metres per hour and a maximum discharge head of 97 metres. The nodular cast iron casing and the mechanical seal are designed for operating pressures of up to 25 bar each, an indispendable prerequisite since the high-rise buildings’ static head often makes it necessary for the piping systems to be designed for 25 bar.

The mechanical seal employed is available in a large number of material variants. The maximum operating temperature should not exceed 140 °C. Each pump is delivered with an impeller whose diameter has been matched to its operating point. This ensures that the pumps achieve the best efficiency point and will not be oversized, as is usually the case with ready-made impellers. In addition, each pump set features an IE2 electric motor whose high efficiency contributes to the new type series cost-effectiveness.

Replaceable casing wear rings on discharge and suction side make for ease of service and maintenance even after long years of operation. Up to a motor rating of 45 kW, motor-mounted speed control systems type PumpDrive can be supplied optionally. For higher ratings, the speed control system is traditionally integrated in a control cabinet.

The new pump series will be presented at this year´s ISH trade fair in Frankfurt/Main, Germany (15 to 19 March 2011).

Mouvex Introduces CC20 Eccentric Disc Pump

Mouvex announces the introduction of the CC20 Eccentric Disc truck transport pumps to the North American market. The CC20 was developed as a vehicle-mounted solution for loading and unloading transports, while its unique design also enables it to be used as a ground-based pumping unit.

Mouvex CC20 pumps incorporate eccentric disc pump technology that consists of a stationary cylinder and disc that is mounted to an eccentric shaft. As the eccentric shaft is rotated, the disc forms chambers within the cylinder, which increase at the suction port and decrease at the discharge port. During operation, the discharge pressure exerts itself against the eccentric disc, preventing it from slipping. This low slip between the disc and cylinder gives the CC20 eccentric disc pumps tremendous self-priming and line stripping capabilities.

CC20 pumps are also compact, providing reduced weight and easy installation. CC20 pumps are available in cast-iron, with optional bronze pistons and stainless steel shafts, and have built-in relief valves to protect the pump from overpressure situations. Special CC20 models are available for “solvents” and “waste oil and lubricants” applications that require the pumping of difficult-to-handle products. The CC20 is available with flow rates up to 158 gpm (35 m3/h) with pump speeds up to 750 rpm maximum. Optional features include drain plugs, direct drive through PTO drive shaft or hydraulic motor drive. Mouvex CC20 pumps are ideal and should be considered for waste oils, chemical applications that involve the transfer of soda, silicates, emulsions, inks, adhesives and resins; petrochemical applications that require the handling of solvents, fuels, crude oil, paraffin, gas oils and asphalt; and lubricants, molasses, oils and clean water.

Highly Efficient Waste Water Pumps

At the ISH trade fair 2011, KSB will present its Amarex/KRT waste water pump series coupled with energy-efficient motors which meet the new European IE3 Premium Efficiency requirements for standard motors.

These pump sets can be supplied with or without explosion protection. Whether operated at rated or low flow conditions, their efficiency exceeds that of standard submersible motors. And they are just as robust!

KSB has developed these motors and manufactures them, making sure they are perfectly matched to the mechanical and electrical requirements of waste water pump hydraulics.

By optimising the electric and magnetic design, the pump manufacturer has already fulfilled the requirements of efficiency class IE3 for its KRT series up to a drive rating of 150 kW.

Dry-installed pumps up to 45 kW can also be driven by the KSB-developed “SuPremE” motor, cutting the losses of the highly efficient IE3 motors by another 15 percent. These motors provide operators with a technology which, already today, more than surpasses the upcoming legal efficiency requirements.
