Pump skid for FPSO shortly before test run

Wednesday, August 6th, 2014 von admin

abb-1klAt the end of 2012, Wepuko Pahnke was contracted by the Brazilian oil production company Petrobras for the delivery and installation of six three-plunger pumps. These pumps are intended for what is known as “well service” on offshore crude oil production ships – the FPSOs = floating production storage and offloading units. The pumps including the drive unit, lubricant supply and pulsation damping are mounted on a skid weighing a total of 48 tons.

Performance characteristics:

  • Installed power 1,230 KW
  • Maximum operating pressure 278 bar
  • Flow rate 120 m³/ h

Lewa: New plunger pump according to API 674

Wednesday, April 16th, 2014 von admin

QuintuplexThis new generation of pumps has splitted gear housings. This special feature significantly facilitates maintenance, permitting the use of a fully balanced crankshaft which generates less noise and vibration, thus reducing wear. The power range was also extended with two quintuplex plunger pumps.  The very short design of these plunger pumps is made possible by the special alignment of the plunger and crosshead. These pumps also have high efficiency, low energy consumption, and a long service life.

High pressure pump unit for liquid CO2

In the extraction of active and valuable substances, aromatic and flavouring substances, the food and pharmaceutical industry is forced to make high demands concerning quality and economy of the extraction process. The CO2-method is therefore preferably used in the extraction of primary vegetable products. The optimal sequence of the process depends on the quality and the controllability of process data in the high pressure section. Efficient industrial utilization of this method requires high reliability and functionality of the most important technical system components. The pumps for increasing the pressure of the liquid CO2 therefore play a key role in the process, because these pumps can be reliably adapted to the CO2-conditions.
