the one that best met the requirements was a Seepex progressive cavity pump with a net positive suction head (NPSH) of less than seven feet. Te Seepex pump is efficient to operate and economical to install. Te pumps operated in high fluid vapour


pressure and low atmospheric pressure. Te altitude at the site is approximately 7000feet above sea level. Other pumps would have required that they be placed at much lower levels than Seepex pumps due to NPSH considerations. In the Rocky Mountain region of Wyoming the added cost of blasting and excavating several feet of almost solid rock is phenomenal.


After the pumps had been put into operation, the customer commented that the Seepex pumps were one of the best investments they had made.


Safety first To remove the residual moisture in natural gas, ethylene glycol must be injected in the gas drying system at high pressure. Tis process demands a pump with above-average reliability, long service life, and low residual pulsation. ABEL’s international customers who are known to maintain a high level of safety use ABEL triplex high pressure pumps from the HP and HPT series. In addition to quiet operation, this pump has an especially low residual pulsation, which is further reduced by optimally placed pulsation dampeners.


When there is not enough natural pressure from the gas left in the reservoir to pump the oil to the surface, the boreholes are filled with water. Tis conveys the remaining oil to the surface. ABEL Series HP and HPT pumps are also ideal for this purpose, because they can be used for pressures up to 25.0MPa (3625psi). Conveying oily bilge water is a similar application. ABEL pumps are used to perform this task on a large drilling platform in the Caspian Sea. Finally, Grundfos has opened a global competence centre in Copenhagen (Fig. 1). Te new centre will aim to gather know-how and develop new technologies that will bring the company to the forefront when it comes to offering sustainable and innovative pumping solutions. “In Grundfos we have already got technologies that can solve some of the challenges. “With this new centre, we are preparing ourselves to become even better, said Soren O Sorensen, group executive vice president. Sorensen estimates the global potential within the area is up to €10billion/y. Te centre is located close to Copenhagen,


in Brondby. Tis location is no coincidence, added Sorensen: “We shall be closer to some of our big customers and some of the educational institutions with which we already have excellent cooperation.” ●
