Heat transfer oil circulation pump acc. to DIN EN 733

Saturday, December 9th, 2017 von admin

Fig.1 The new NKX heat transfer oil circulation pump

The pump manufacturer Dickow has developed a new pump line NKX for circulation of thermal oil. The pump casing is designed for 16 bar and 350 °C. The new pump line extends the application limit of the previous NKLs-type. The new NKX will replace the series NKLs with exactly the same dimensions in future.

The NKX is used as a circulation pump for hot oils in industrial heating plants/units. The performance range covers capacities up to 400 m3/h and differential heads up to 90 m in 50 Hz services; and capacities up to 2,500 US-gpm and differential heads up to 400 ft in 60 Hz services. The dimensions and performance range of these centrifugal pumps are according to DIN EN 733, that means range is subdivided into different pump sizes in order to achieve best efficiency for all service conditions inside the envelope.

Multiphase pump installation allowing wells to come back to production

Wednesday, November 15th, 2017 von admin

Crosbys Creek Oil & Gas  LLC, based in Ridgeland, MS,  is an independent American producer producing in Choctow County in Northern Alabama, USA. These fields are older and have produced oil and gas for many years.  Over time the natural reservoir pressure has dropped off to a point where some wells are not able anymore to overcome the back pressure generated by the surface flow lines and the first stage separator of the process facility. The company had heard about multiphase pumping. This economic alternative caught the interest of the management as the production was expected to remain interesting for years to come.

Hot water version

The new CombiTherm Plus pump provides transfer of hot fluids without the need for additional, external cooling systems. The pump is available in two configurations suitable for the pumping of hot oil or hot water and provides an highly efficient and pumping solution. The air-cooled CombiTherm Plus pump provides transfer of hot oil or hot water in a wide range of applications including

  • injection molding,
  • chemical processing,
  • asphalt / bitumen and tar processing,
  • deep frying systems,
  • steam generators,
  • fuel heaters and
  • heat recovery systems.

The pump keeps fluid temperatures uniform to ensure processes are efficient while its design protects seal faces and bearings from the heat of the fluid; ensuring durable, low maintenance, long life operation.

Hermetic: 12-stage canned motor pumps for ethane cracker plant

Monday, June 6th, 2016 von admin

IMG_1941The actually supplied two canned motor pumps, with “tandem” design, convey the medium [C3 fraction with propylene as main constituent] at a temperature of 22 °C. The differential head [H] is 379 m at a flow rate [Q] of 7.8 m³/h. The pump units are designed for a nominal pressure of 40 bar and have temperature- and level-monitoring features. For online monitoring of the hydraulic axial bearing, a rotor-position monitoring feature is also provided.

The special tandem design of the multistage pumps results in minimal shaft deflection and load relief at the slide bearings. The “ZART” (Zero Axial and Radial Thrust) technology ensures a contact- and wear-free running of the rotor unit.

Sundyne: API 685 Sealless Pumps

Thursday, April 21st, 2016 von admin

GSPV_2100x1610A major Malaysian refinery is currently upgrading equipment throughout their facility. As refining and petrochemical processing operators around the world face increasing pressure to comply with stringent health and safety regulations, they are replacing their aging single seal pumps with efficient and highly reliable sealless magnetic drive pumps. These pumps eliminate dangerous leaks and put an end to costly seal maintenance.

The customer required a cost effective and highly reliable pump to replace existing API 610 vertical pumps with single seal systems that are prone to leakage and emissions. Sundyne specified the GSPV API 685 sealless magnetic drive vertical pump for their application. In total, Sundyne provided 6 vertical and 2 horizontal API 685 pumps to directly replace the old sealed units handling stripper reflux and debutanizer reflux applications.

Sundyne: New low NPSHr, high-flow pump

Thursday, January 14th, 2016 von admin

sundyneThe Sundyne LMV-803Lr is an API 610 compliant pump available in either OH3 or OH5 motor mounting configuration that provides ultra-low NPSHr performance – approximately 5 ft (1.5 m), across the entire performance range – for flows to 800 GPM (180 m³ / hr) and heads to 1,000 ft (305 m).

The ultra-low NPSHr allows the pump to be installed at grade level, eliminating the expense of installation in a pit and performing maintenance in a confined space. The vertical design is ideal for use in refineries, NGL, petrochemical and chemical plants, as well as handling light hydrocarbon handling services, such as bottom pumps for de-ethanizers.

CP: New magnetic drive centrifugal pump up to 750 m³/h

Tuesday, October 13th, 2015 von admin

cpThe Swiss pump manufacturer CP Pumpen AG has put a new pump size on the market. The new magnetic drive pump, MKP 250-200-315, enhances the MKP series. These pumps are – according a company’s information – “considered high-performance, energy-efficient, sturdy and very safe – regardless of which medium is pumped. CP’s development team was able to implement all of these product properties in the new MKP 250-200-315.”

“The demand for pumps with a large flow volume had increased in the past. With a volume of up to 750 m3/h, the new MKP is complementing our series with a size that is important for the market”, says Heinz Mathys, Marketing & Sales Director and member of the CP Management Team.

Lewa: New Triplex process diaphragm pump

Thursday, June 25th, 2015 von admin

abb1The G3M, a heavy-duty, medium-sized triplex drive unit, was originally developed to bring re-liquefied boil-off gases from LNG tankers to a high pressure level, rendering these gases usable for the ships’ propulsion system. As a rugged workhorse, it is also ideal for various other applications, including use in the chemical industry or for offshore applications on oil platforms. The Lewa Triplex G3M process diaphragm pump was one of the main exhibits of Lewa GmbH at Achema 2015.

The G3M is an intermediate size product in the Lewa portfolio that attains a maximum output of 200 kW thanks to its stroke length of 120 mm and a rod force of 125 kN. It is intended for use primarily in the oil and gas industry, as well as the chemical process industry. The chief application in the former sector is injecting monoethylene glycol and methanol. In the process industry, a wide variety of pumping tasks in pressure ranges between 40 and 750 bar can be managed. Other possible applications include handling highly flammable materials such as vinyl acetate, slurry in the wet oxidation or high-pressure metering of liquid ammonia.

Lewa: Safe pumping of sour crude oil

Thursday, May 7th, 2015 von admin

SauerölpumpeCritical applications of conveying mixtures of acidic hydrocarbon/water to the washing system are a challenge for any pump manufacturer. This was also the case in one recent project Lewa handled in the Emirate of Abu Dhabi. Lewa have designed and supplied 16 pumps to a major construction company in Abu Dhabi specifically designed to handle this critical application. Two processes required to pump

  • liquid hydrocarbons from the flare knock-out drum or the blow-down drum respectively and
  • convey the acidic hydrocarbon/water mixture back into the oil line to the washing system

Since the differences in these two processes are only minor, it was possible to supply 16 mechanically identical pumps of the Ecoflow series, driven by 55 kW electric motors.
