Heat pump From Wikipedia, the free encyclopedia For theoretical background, see Heat pump and refrigeration cycle.

Well fluids enter the pump through an intake screen and are lifted by the pump stages.Other parts include the radial bearings (bushings) distributed

Our Customer has a plating application that required the mixing and re-circulating of chemicals, an 18% Zinc solution @100 F. The customer also needed a sealless solution that could at times, run dry. The pump they used at that time was from one of our major competitors, and was not working well

A self-priming pump was proposed bare shaft and with oversized support, characterized by the use of a flexible joint for coupling with the diesel engine. PVDF was selected as the pump material (for its high and well known characteristic

I have customers off-grid that are always looking for a new alternative. The normal electrical generation system is a diesel-powered generator, and the diesel has to be shipped in by barge- thus, we are talking significant costs for generating electricity (typically in the $0.15 to $0.20 per kW/hr)...

Large vertical pumps in water service may at times face the problem of reverse flow causing reverse rotation. The reverse flow may arise due to failure of check valve or tripping of one pump in case of parallel operation. Pumps can be provided with a ratchet arrangement to overcome the problem of r

The V60N-130 joins the V60N Series of axial-piston pumps. The Series now consists of four different sizes with displacement volumes up to 8 in.3/rev, working pressures of up to 5,800 psi, and peak pressures of up to 6,500 psi. All pumps have swash plates and provide required displacement volume without over or underdimensioning the pump output. read more

MANSFIELD, Ohio--(BUSINESS WIRE)--The Gorman-Rupp Company (NYSE MKT: GRC) reports that its Patterson Pump Company subsidiary has been reaffirmed as the supplier of pumps for the Permanent Canal Closures and Pumps (PCCP) project with the U.S. Army Corps of Engineers, New Orleans District. This significant project was originally awarded in October, 2012, but was challenged by unsuccessful bidders. The PCCP Constructors, a Joint Venture, which will be utilizing Patterson Pump Company pumps, has rec

A company weeks away from the planning decision on what is thought to be the first small-scale commercial electricity pumped storage scheme to be built in the UK, has been awarded a grant by the Department of Energy & Climate Change aimed at accelerating Britain's move towards renewable energy. Already the UK's centre of expertise in small-scale pumped storage, the Quarry Battery Company will use the grant to learn even more from operators in other countries around the world. Pumped storage uses low cost off-peak electricity to pump water from a lower to an upper reservoir. At times of peak demand the water is allowed to flow back downhill through a turbine to re-generate electricity. The technology was thought only to be viable when used on a large scale, such as the 1800MW facility at Dinorwig in north Wales. Few locations in the UK are suitable for such installations. However, QBC is confident that much smaller scale pumped storage is commercially viable. QBC's proposed scheme for the old slate quarries at Glyn Rhonwy would output around five per cent of the electricity of nearby Dinorwig. The company is currently in talks with a number of potential partners about the funding of the ?100m construction phase of the scheme. A growing number of energy experts and environmental groups including Friends of The Earth believe that the development of many such smaller sites will enable the UK to slash its dependency on fossil fuels and more easily meet its climate change obligations. Greater pumped storage capacity would resolve a central problem with renewables - that their generation ability is weather- and time-dependent, and therefore intermittent. Pumped storage sites would absorb power from wind turbines and other renewable sources, then release it back into the electricity grid at times when there is no wind, sun or tide. Conventional power stations which must currently be kept on standby to fill these gaps in generation could be stood down, saving further costs and carbon emissions. QBC managing director Dave Holmes said, "The potential partners we are talking to about the construction phase at Glyn Rhonwy are excited, not only at the projected returns but also at the opportunity to get in on the ground floor of an industry that has the potential to help end Britain's reliance on fossil fuels for electricity generation. "We know we can make pumped storage work on a much smaller scale than before, but we think there's still much to learn from how it's done in other countries. In addition, there may be technologies and techniques in parallel or quite unrelated sectors that we can apply or adapt to make pumped storage even more efficient and less costly." The Quarry Battery Company (www.quarrybatterycompany.com) was founded from ideas that originated at the Centre For Alternative Technology near Machynlleth. QBC's scheme for Glyn Rhonwy near Llanberis was designed in conjunction with AECOM, Gwynedd Council, Cadw, Countryside Council For Wales and Environment Agency Wales. The company already has options on other sites in England and Wales. -ends- Further editorial information: QBC: Dave Holmes - 07999 552875 or 01787 476966

Out of sight (and smell), natural gas slowly bubbled up into Norma Fiorentino’s private water well near the town of Dimock in northeastern Pennsylvania--in the heart of the new fracking boom in the U.S. Then, on New Year's Day 2009, when a mechanical pump flicked on and provided the spark, Fiorentino's backyard exploded. She and many others blame the blast on fracking --the colloquial name for the natural gas drilling process that combines horizontal drilling and the fracturing of shale deep underground with high-pressure water to create a path for gas to flow back up the well.
