Rising Oil & Gas Demands Boost Pump Market

Rising Oil & Gas Demands Boost Pump Market As the demand for oil and gas keeps going up, customers want higher quality pumps that last longer, says market analyst company Frost & Sullivan. They also want intelligent pumping systems to control and monitor pump performance. The market for pumps in the European oil and gas sector exceeded $959 million in 2006 and is expected to reach $1.2 billion by 2013. Challenges for European pump manufacturers, however, include stiff competition from lower-cost pumps made in Asia as well as the increasing need for energy efficiency and emission controls.

Solar System Powers Water Pumps

Solar System Powers Water Pumps The Valley Center Municipal Water District in San Diego, CA, is building a 1.2 MW solar system capable of powering multiple 350 hp electric pumps. Key to operation: drive technology that correlates motor speed with "maximum power produced by the PV array." From dawn to sundown, 365 days a year, a single-axis tracking array covering five acres will send solar power for pumping during high power consumption hours.

When to Use Variable Speed Drives?

When to Use Variable Speed Drives? The use of variable speed drives to power drinking water and wastewater pumping systems is increasing, but they cannot be justified for all applications. To decide when to use variable speed pumps, you have to apply "Affinity Laws," or calculations that show how pump performance varies with speed. Here's how.

Cutter Pumps Chop Grass for Gas

Cutter Pumps Chop Grass for Gas Macerate 5,000 tons of kitchen and garden waste each year — that's the job these Landia cutter pumps are successfully completing, reports Process and Control Today. Employed at a biogas plant in the UK, the pumps prepare food waste and grass for anaerobic digestion.

Pumping Painting Products Poses Problems

Pumping Painting Products Poses Problems Pumping coatings, resins, and solvents can be a problem because of leaks and the effects solids can have on the pump itself. Valspar's paint and coatings plant in Deeside, UK, uses air-operated double-diaphragm pumps that feature Teflon diaphragms. The plant also replaced clamp-banded pumps with fully bolted pumps, which are said to handle low-viscosity fluids much better.

No More Changing Pumps Every Shift

No More Changing Pumps Every Shift Pumping latex is tough because of adhesion and coagulation, requiring regular replacement, many spare pumps, and extensive overhauls. At Polimeri Europa, pumps were changed nearly every shift. Amarinth designed a pump that could run three weeks without maintenance by using a scalloped impeller and electropolish to create low-friction surfaces. Labor costs are down 85%.

Moving Manure with Hose Pumps

Moving Manure with Hose Pumps Hose pumps can be used for moving abrasive dairy waste, such as cow manure laden with sand. Hose pumps have no seals, valves, or moving parts so the abrasive slurries and corrosives can't damage internal parts. A typical hose pump costs about $14,000 — about $2,000 more than a progressive cavity pump — but maintenance costs are much lower.

Changing Controls for a Chicago Condo

Changing Controls for a Chicago Condo When the water pumping system in a Chicago condo started to show its age, investigation revealed an outmoded triplex constant speed system, typical of systems built back in 1972. McGuire Engineers recommended a quadraplex (four pump) variable speed control system, and it was installed in the middle of the night when water usage was lowest.

Unwritten Pump Rules

Unwritten Pump Rules Pump consultant Larry Bacchus offers a "cheat sheet" of three generally accepted rules on how to stand next to a pump and decide if it is sick or healthy. He says a pump will tell you about its problems for hours, days, or weeks before it breaks down; you just have to know how to interpret what it's telling you.
