connected, so that the shaft seal does not run dry. Dry running will damage the shaft seal and could lead to a damaged pump. Alfa Laval is a global provider of spe- cialised products and engineering solu- tions based on key technologies of heat transfer, separation and fluid handling.

Wear and tear is natural, but servic- ing equipment regularly can ensure operational reliability and help maintain performance. Preventive maintenance reduces unplanned stops, increases equipment lifetime and reduces workplace accidents. Regular service and maintenance of valves allows them to perform optimally. A simple preventive maintenance programme can prolong the lifespan of the valves. For rotary lobe pumps, the oil level in the gearbox should be checked regularly and re-filled when necessary, as well as following the re-lubrication schedule in the manual. Tank equipment should be regularly maintained following scheduled service intervals, to keep the equipment in good condition. Centrifugal pumps should be checked to make sure water has been

Actuated ball valve assemblies SSP, a specialist in stainless steel and nickel-based alloy tube fittings, valves and tubing, has extended its instrument ball valve lines to include actuated ball valve assemblies. Options include a wide range of sole- noids and limit switches, dual mounted assemblies, and an assortment of other features for specific applications.

+149°C (-65°F to +300°F), and a wide range of solenoids and limit switches for standard, intrinsically safe and explosion-proof environments. Actuators are designed with precision honed bodies, rugged tooth design, high visibility position indication, high cycle-life wear pads and operating air pressures from 40 to 150 psig. In addition to the standard offering, SSP can source and assemble packages to customers’ specifications. “All components are selected to optimise the operation of each valve and actuator for reliability and durability,” stated Stuart Noble, product engineer. “SSP assemblies are factory tested and SSP stands behind the entire assembly: valves, actuators, hardware and accessories. There is never a question of responsibility for components manufactured by different suppliers.” SSP Fittings Co – USA customer.inquiries@mysspusa.com www.mysspusa.com

The new actuator line includes two- way and three-way valve actuators with options for corrosion-resistant coated and stainless steel housings, temperatures ranging from -53°C to

The standard offering includes 90° and 180° double acting, spring to open, spring to close, and spring to centre actions actuators.
