Gather: From laboratory to production via pilot plant

Tuesday, April 4th, 2017 von admin

A process generally undergoes initial development within a laboratory and is then made production ready in pilot or mini plants. During this scale-up, a range of different problems can emerge, e.g., in the way temperatures behave. In a laboratory, a process may be endothermic but becomes exothermic in production. How pumps behave in relation to peripheral equipment can change under full-scale production conditions, Sven Borghoff describes a coordinated pump and drive concept which makes scaling up easier.

Dosing pumps with multifunctional extensions for different pump types often used in laboratories generally have no particularly high temperature or pumping ranges. However, when scaling up, these aspects take on major significance. Gather uses its magnetic-driven pumps (Fig. 1) here. They are available in such a broad range that when scaling up from the laboratory to production via a mini or pilot plant, the pumping and control technology can be retained. The company cooperates with the chemical industry, institutes and universities to make process development from initial laboratory trials through to production easier.

Blackmer: Heavy duty sliding vane pumps for industrial applications

Thursday, March 16th, 2017 von admin

The new GNX and GNXH Series Sliding Vane Pumps are designed to handle a wide range of non-corrosive, non-abrasive industrial liquids and petroleum products. Manufactured with a large operating range, these pumps offer high flows and high pressure. They are currently available in 2- and 2.5-inch flanged port sizes. Larger 3- and 4-inch flanged port sizes will be released later this year. Combined, these sizes provide flow capacities ranging from 20 to 500 gpm (76 to 1,893 l/min) at working pressures up to 175 psi (12.1 bar).

Wilden: AODD Pumps now available in Ductile Iron

Thursday, February 2nd, 2017 von admin

The Wilden Advanced FIT pumps feature bolted product containment and easier maintenance. No repiping necessary, the Advanced FIT pumps precisely fit bolt-to-bolt and pipe-to-pipe in existing fluid-handling piping systems. The FIT pumps come equipped with the wetted path that minimizes the number of fasteners and allows for single socket reassembly for faster, easier maintenance. These pumps also come equipped with the energy-efficient Pro-Flo Shift air distribution system.

Daurex: An evolution of progressing cavity pumps

Monday, July 4th, 2016 von admin

IntelliflEx by DAUREXIntelliflEx is the name of a completely new approach towards design and technology for progressing cavity pumps. This highly efficient pump, based on the valve-less positive-displacement pump technology combined with intelligence of computer and software.

All components are reflecting the fundamental ideas which lead to the innovation: Make progressing cavity pumps greener:

  • Stainless steel for the housing of motor and drive,
  • natural granite stone instead of cast iron are not only eye catching design details.

Almatec: High-Pressure Pump Series

Monday, July 4th, 2016 von admin

Almatec-AHD_AHS SeriesThis new high-pressure pump series AHD/AHS are developed for applications up to 15 bar (218 psig) such as filter press applications.

The “D” in AHD stands for Duplex, which means the reinforcement of the drive pressure is more than 2:1 by the internal pressure boosting stage. This is achieved thanks to a maximum drive pressure of 7 bar (100 psig), which allows the AHD to build up discharge pressures up to 15 bar (218 psig). AHD Series pumps are available in three sizes (AHD 15, 25 and 40) with maximum capacities of 4, 10 and 20 m3/h (17, 44 and 87 gpm).

The new AHS Series, which does not include an internal pressure booster, features an extremely rugged housing making it suitable for higher discharge pressures. The “S” in AHS stands from Simplex, meaning the drive pressure is transferred to the medium in a ration of 1:1.

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: 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.
