WORLD PUMPS
Dosing chemical and fluorinated products The Roytronic® generation of LMI electronic dosing pumps has been introduced by Milton Roy Europe. According to Milton Roy, the Roytronic is accurate, sturdy, economic, and most suitable for use with chemical and fluorinated products, and amines. With four versions and a large variety of liquid ends available, the Roytronic has a thick wall IXEF reinforced thermoplastic

construction, plus integrated metal-plastic structural and magnetic components resulting in vibration and shock resistance. In addition, strong automotive type wiring and electrical connectors make this model sturdier than previous versions. The pump has a maximum output of 12.1 l/h, a maximum pressure of 17.3 bar, and a can handle up to 50oC pumped chemical temperature. www.dosapro.com
Improved sealing for pumps and valves
Rotork has introduced a new electric actuator for the operation of process control valves.
A new electric actuator for the operation of process control valves has been developed by Rotork – manufacturer of electric, pneumatic & hydraulic valve actuators. The CVA range provides continuous, repeatable modulating control with a programmable fail to position option.
The Perlast® G75M has been designed to improve sealing in many extreme conditions.
Precision Polymer Engineering (PPE) has launched a new multipurpose perfluoroelastomer (FFKM) compound, which it claims offers outstanding resistance to a broad range of chemicals and has an extremely low compression set. The Perlast® G75M aims to improve sealing in extreme conditions, including high speed rotation, high temperature and high pressure applications. With a compression set of 14%, the G75M has been designed to increase the efficiency and lifespan of seals. Designed to be particularly effective in mechanical seals and multi-substance chemical

plants, the G75M can be used in pumps, valves, couplings and fittings. The long term sealing efficiency of G75M provides manufacturers and processors a number of benefits, including extended maintenance intervals, reduced down-time, lower cost of ownership and improved production efficiencies. With modulus and hardness optimized to suit the majority of sealing applications, G75M can be moulded into O-rings (any size up to 2 m/6.5 ft diameter) and custom shapes. www.prepol.com
Operating on an industry-standard 4-20 mA control signal or digital bus, the resolution, repeatability and hysteresis performance of the CVA is <0.1% of full scale.
Available for the direct-drive actuation of linear or quarter-turn control valves, the CVA features include a double-sealed enclosure, whereby internal electrical components are permanently protected from the effects of the operating atmosphere. The IP68 dust tight, watertight and temporarily submersible enclosure is universal to all models in the CVA range, including those with hazardous area approvals. www.rotork.com
Heavy-duty motor pump achieves extra efficiency A range of large stainless steel motor pumps designed to provide flows of up to 165 l/min, and heads up to 63 m, has been introduced by Australian Pump Industries. The Aussie Jetmax uses single phase power to achieve effective flow/pressure combinations, making them suitable for domestic and professional markets. The power is provided by heavy duty single phase IP55 grade electric motors that are totally enclosed and fan cooled. These
motors are vermin proof, and combined with the high tech jet pump design, can operate with maximum efficiency. The pumps come with heavy duty 304 grade stainless steel bodies and carbon ceramic mechanical seals. Shafts are manufactured from AISI 431 grade stainless steel, and the impeller is either high grade polycarbon, or bronze for corrosion resistance. www.aussiepumps.com.au
