sure pump is capable of gener- ating a maximum flow rate of 225 gpm and a maximum pres- sure of 500 psi.

means that it does not require further treatment, thereby sav- ing on chemicals, and the heat content of the returned conden- sate reduces fuel costs.

Now, thanks to the introduc- tion of a new compact and effi- cient range of condensate pumping sets from Gestra (UK), recovering condensate has been simplified. Each fully packaged system comprises a horizontal receiver mounted on a support frame which also provides the housing for duty and stand-by centrifugal pumps, and pipe- work incorporating isolation valves on the suction side and check valves on the discharge side. The sets also include an IP55 rated steel control cabinet with three position selector switch for manual or auto changeover pump selection and a seven day timer switch for changeover sequencing.

The receiver vessel is avail- able in galvanised mild steel, copper or stainless steel and incorporates a four probe level sensing unit, sight glass and drain cock. The units are designed to handle condensate up to 95°C although higher temperatures can be accommo- dated if required. The range comprises over a dozen models capable of handling discharge rates in excess of 20 000 kg/h.

Off-the-shelf seal monitoring

Pump users now have a cost- effective alternative in selecting support systems for dual seals used for light duty services in industries such as food process- ing, chemical processing, phar- maceuticals and pulp and paper. John Crane Lemco’s new Model RE-1203 and RE-1205 reservoir systems reliably con- trol emissions and monitor per- formance of both non-pressur-

ized and pressurized dual seal arrangements. Based upon high- er end systems, the Models RE- 1203 and RE-1205 offer a con- sistent level of reliability for lighter duty applications with temperatures up to 200°F (93°C) and pressures up to 200 psig (13.8 bar g).

Pressure and level sight gauges located on the two gal- lon, stainless steel reservoir pro- vide a means for monitoring seal performance. The pressure gauge reports any fluctuations in pressure that could affect the sealing environment, and the level gauge reports fluid level increases or decreases in the reservoir that could indicate un- acceptable condition changes, including leakage.

As an option, users may add electrical pressure and level switches to detect any anoma- lies and alarm if predetermined set points are violated. Switches can also be wired to shut down the equipment in the event of an alarm. In the dual non-pres- surized arrangement (tandem), the primary seal in the pumped liquid environment operates at normal seal chamber pressure, and the secondary seal in a buffer fluid operates at a lower pressure (typically at atmo- spheric pressure). Because of its higher running pressure, the primary seal allows leakage into the secondary seal. The leakage is then contained by the reser- voir until the fluid is properly disposed. Additionally, the sec- ondary seal is cooled and lubri- cated by the buffer fluid circu- lating through the reservoir.

Water pumps make a point of efficiency

Ingersoll-Dresser Pumps’ en- hanced efficiency packages for

some of its LNN range of water pumps add several points of efficiency to the pumps’ perfor- mance. This should realise sig- nificant energy savings and reduced power costs. Calcu- lations show that in some cases the pumps can offer a three year payback based on energy savings alone.

The LNN pump is a reliable product offering quiet opera- tion and good NPSH, all of which are key issues for the water industry. Designed for the full range of water supply and water treatment applications in the water industry, the LNN range offers capacities up to 15 000 m3/h (4170 l/s) and heads up to 250 m. Operating pressures are up to 30 bar and operating temperatures are standard up to 80°C and option- ally up to 150°C.

There are several other fea- tures in the LNN design. Hydraulic balance is provided by a double entry type impeller at the centre of the pump, which is keyed to the shaft and located by external nuts. Dynamically balanced impellers give smooth running and lower maintenance costsThe symmet- rically positioned double dis- charge volutes balance hy- draulic radial loads over the full operating range of the pump. This minimises shaft deflection and bearing loading, leading to improved reliability and re- duced maintenance costs.

The robust shaft in the LNN pump minimises deflection at the seal faces and improves seal life. Sleeves eliminate wear to the shaft and are positively driven by the impeller key to prevent spinning under packing drag. O-ring seals are fitted at the impeller end to prevent leakage and the sleeves termi- nate before the bearing housing as added security to prevent leakage into the bearings.
