Traditionally used as a cement binder for hot-slab paving, liquid bitumen must be handled at very high temperatures in order to keep it at a workable viscosity. However, even at high temperatures liquid bitumen can be an extremely viscous and shear-sensitive product. Therefore, shipyard operators and tanker owners demand a pumping technology that has been specifically designed to transfer highly viscous liquids over great distances. Realizing the importance for pumping equipment that feature the design and performance characteristics required for transferring highly viscous liquids, Blackmer offers its S Series Twin Screw models for these marine applications.

UK specialist pump manufacturer Flotronic Pumps Limited was founded by Lew Norris in 1981. The engineering design consultancy ‘Norris Brothers’ had been involved in the design of specialist pumps since 1952. Lew Norris’ new company pioneered the air-operated, double-diaphragm ‘One-Nut’ pump. Flotronic’s ‘One-Nut’ design allows quick pump disassembly for inspection, cleaning and maintenance – delivering a massive benefit for pump users in terms of reduced down-time, particularly as the pump can be inspected or maintained in line without disconnection of pipework. Flotronic remains the only British-owned specialist manufacturer of air-operated, double-diaphragm pumps in the UK.
Kirloskar Brothers Limited (KBL) has partnered for food sufficiency with the Government of Senegal, a country in Western Africa. Before 2005, Senegal’s irrigation infrastructure was under-developed. Government of Senegal was not able to meet the expected food sufficiency levels of the country because of the haphazard irrigation techniques. For achieving better means of livelihood, the Government of Senegal felt the urge to resolve the issue of unemployment among the rural youth and stop their exodus to cities.
The major challenge faced by Senegal was the need for skilled labour. In North Senegal, lack of proper irrigation equipment was identified as the foremost problem. Even though there was abundant water available in the Senegal River, there was no mode to direct it to the fields in sufficient quantities required to irrigate rice. Alongside, South Senegal was grieving over existence of excessive saline surface water for irrigation purposes. The feasible alternative was to tap ground water in order to receive a supply fit for the yield.
This year’s ISH trade fair in Frankfurt will see KSB present a new 230 V version of its motor-mounted PumpDrive Eco variable speed system. Available for motor ratings ranging from 0.12 to 1.1 kW, this new version has been specially tailored to the requirements of HVAC applications.
PumpDrive Eco features sensorless differential pressure control which comes preset for use with Etaline L. All key parameters relating to pump and motor data are also set at the factory. This reduces the time required for pump set commissioning.
Alongside wireless Bluetooth modules for permanent installation supplied optionally, Bluetooth couplers are now also available. These can be plugged onto the service interface of PumpDrive Eco from the outside. This arrangement improves usability by also allowing communication with systems that do not have their own BT interface. The myPumpDrive app enables users to communicate with the system and make settings via smartphone.
As a replacement to conventional submersible pumps, the manufacturer Hermetic supplied two 8-stage, sealless canned motor pumps. The distinctive feature of the transformation was the customized adaptation of the pumps to the existing plant and its vessels. The pumps were designed for easy installation in the existing tank (with a diameter of 500 mm). The customer, a Swiss fine chemicals manufacturer, thus saves the costly, time-consuming conversion of the existing systems in its production plant.
The high-efficiency circulator range Calio SI type series are intended for use in heating, air-conditioning and solar power systems where they facilitate automatic operation with constant-pressure or proportional-pressure control as well as operation with 0-10 V setpoint input or external control via PWM signal in accordance with VDMA-Einheitsblatt [Standard Sheet].
On the HMI, Dual and EcoMatch variants the user can select the required mode of operation via two pushbuttons on the control panel.
Over the past years Wanhua Chemical Group, the world’s largest producer of MDI (Methylene diphenyl diisocyanate) has been experiencing rapid domestic and global growth. As one of Wanhua’s top suppliers for critical equipment for more than 10 years, Richter’s global presence has contributed to the expansion of Wanhua with pumps and valves for the most corrosive applications. Reliable quality and top notch service have been key to our long standing cooperation.
Chemtech World Expo – February 14-17, 2017 – is one of the largest events for the chemical industry. 600 exhibitors from 20 countries expect up to 40,000 visitors. At the same time eight international conferences and about 150 speakers are offered. In the German pavilion, the German community stand, organized by the VDMA, the company Bungartz will present the concepts of its problem-solver pumps at stand C6A, which also have a high intrinsic safety:
- Wear and corrosion resistant pumps for the fertilizer industry
- Pumps with hydrodynamic shaft seal
- Continuously dry running magnetic driven pumps for liquids with large solids contents
- Cavitation-free pumps with an NPSH value <0.1m
KSB has been contracted to supply 22 power station pumps for the new Vietnamese Long Phu-1 power plant. The plant’s two 600 MW units are currently being built by a Russian engineering contractor. The complex is situated 20 kilometres east of Soc Trang city, on the right bank of the Hau River.
Included in the order are six boiler feed pump sets. The main and associated booster pumps are driven by 15,200 kW high-voltage electric motors. A geared variable speed coupling installed between the main pump and the motor varies the speed to achieve different operating parameters. Each pump set has been designed for a maximum flow rate of 1,200 m³/h and a head of 4,400 m. The boiler feed water temperature is expected to be 175 °C. To reduce energy consumption, the seven-stage pumps are equipped with optimised hydraulic systems which have proven their quality many times over.
Sohar SWRO Company LLC is the EPC Contractor for Sohar IWP and has signed several contracts with Sulzer to supply pumps for the new 250 000 m³/day independent desalination plant in Sohar, Oman. Commercial operation is scheduled for 2018.
The contracts include the manufacturing, testing, packaging, and installation supervision of the main centrifugal pumps. Seawater intake for the plant will be provided by Sulzer’s three big SJT vertical turbine pumps that will be installed at the nearby industrial port pumping station.
