Hermetically sealed Twin-Screw Pump for chemical and petrochemical sectors

Monday, June 18th, 2018 von admin

ITT Bornemann launched a new hermetically-sealed pump, named SLW, at Achema 2018 in Frankfurt, Germany. This pump serie uses a magnetic coupling for a hermetic pump drive. With the sealed fluid chamber, critical media with harmful substances are confined to the pump and not released into the environment.

  • The design allows the two screws to convey the product and transmit the torque.
  • The single-volute design is also compact and requires a small footprint for installation.
  • The product is lubricated with inboard bearings.
  • The less-wear parts design leads to low-maintenance, resulting in high MTBF.

New plunger pump head reaches up to more than 1,000 bar

Friday, April 13th, 2018 von admin

The plunger pumps feature an integrated gear, which enables very compact construction with maximum efficiency.

For the purpose of upgrading a cracker in a Chinese refinery a total of five plunger pump skids should be brought into operation by Lewa. Those in charge of the project opted for three triplex and two quintuplex plunger pumps in accordance with the API 674 standard. These pumps are equipped with the new KMC-L pump head with reduced clearance volume. This head consists of a single forging: The suction manifold is integrated as a result, allowing for a reduction in the sealing surface and thus in any potential leak points. An additional advantage is the fact that the suction side can be designed to handle backpressure, eliminating the need for a safety valve in the suction line. The new design makes it possible to realize pressures up to 1,075 bar. All pumps in use have been produced in Germany and mounted to a complete system in the Chinese plant.

These plunger pumps have a drive output of 260 kW and a flow rate of 25 m3/h. The suction pressure loss of the pump heads is very low, therefore a low suction pressure is needed and it is often possible to operate without a booster pump.

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.

KEPL: Pumps for highly critical refinery application

Tuesday, February 24th, 2015 von admin

IMAG1498KEPL has shipped the first set “5-stage BB3” pumps to Reliance Industries Limited (RIL) for J3 Project at Jamnagar in Gujarat, India. API 610 standard BB3 pumps are Between Bearing Axially-Split case pump.

BB3 pumps are designed for high temperature and high pressure fluid transfer applications. Its near-centreline mounting design makes the BB3 pump suitable for various refinery applications subjected to the ISO or API criteria for flammable hydrocarbons. The pumping temperatures range for the BB3 Pump is from 5 degree Celsius to 200 degree Celsius and its capacity is upto 2500 m³/h.

Magnetic Couplings Seal New Zero-leakage API 685 Refinery Pump

Wednesday, January 15th, 2014 von admin

MAK 685 KSBKSB South Africa in cooperation with EagleBurgmann specified high-efficiency magnetic couplings to seal the shaft for the newly designed API 685 process pump. It was also decided to use the couplings from the proven MAK685 series because they reliably cover a broad application field in the higher pressure and performance range.
