Viking sealless gear pumps can reduce pump downtime
Viking’s range of internal gear pumps have a robust sealless design.
Viking has developed Viking Mag Drive® 855 Series, a range
of internal gear pumps which offer exceptional reliability
through their robust, sealless design, which eliminates seal leakage, the company reports. The pump’s driver turns an outer magnet, whose force passes through a stationary O-ringsealed canister to turn an inner magnet, which drives the pump shaft without the need for seals. Features of Viking's Mag Drive 855 series include adjustable end clearance to maximize efficiency and ANSI or DIN-flanged ports for sealing reliability. They may be close-coupled to NEMA C or IEC B5-flange motors, or long coupled.
design allows short-term run dry capabilities, ensuring long field life and reduced downtime, Viking says. This can greatly reduce the possibility of damage from priming and accidental empty tank situations. Additionally, the Mag Drive 855 pumps are designed for easy draining, disassembly, repair and reassembly, with a minimal number of parts — keeping maintenance costs low.
The pumps’ thrust-controlled
This series of pumps offers flow rates of up to 135 gpm, with pressures up to 200 PSI, at temperatures ranging from -60° to 500°F (-51° to 260°C).
(sizes from 0.5-140 ml), making possible extremely low flow (0.002 ml/hr) to exceptionally fast flow rates (55.1 ml/minute). The new model delivers fluids with high accuracy (± 0.35%) and pulseless flow.
Harvard Apparatus’ Syringe Pump.
Syringe pump fitted with silent motor Harvard Apparatus’ Physio 22 Syringe Pump has been fitted with a new motor which renders it electrically silent, the company reports, with no radio frequency interference or electromagnetic field interference. The Physio 22
Syringe Pump is said to be perfect for use in any isolated environment; and can be operated inside a Faraday cage. The Physio 22 Syringe Pump accepts a wide range of syringes
New variant of dosing trailers for emergencies ProMinent Fluid Controls, UK has produced a new variant of its fully equipped mobile chemical dosing trailers for UK Water Authorities. This latest version is designed for dechlorination duties and can be readily transported to any location for emergency dosing of chemicals to maintain drinking water supplies. It can be used when the emergency reservoirs created by many water authorities need to be brought on line to supply potable water, or for dechlorination following emergency disinfection of a water supply. The dechlorination trailer is equipped with two 140l tanks for sodium bisulphite and has four gamma/l precision dosing pumps, arranged in duty/standby configurations. Two pumps have output capacity up to 16l/hr, while the other two operate up to 10l/hr. Power is supplied via a compressor. Built-in failsafe facilities include level alarms for each tank and an auto-

changeover in the event of pump failure. Other trailers available from ProMinent are equipped for sodium hypochlorite dosing or with a Bello Zon chlorine dioxide generator to allow chlorine dioxide to be used as the disinfectant. This means that an emergency disinfection system can be deployed anywhere within a local area within hours should there be a disinfection failure to a drinking water supply. The units can also be used to provide 'top up'disinfection during routine maintenance on parts of the distribution system.
