more precise and repeatable flow setting.
The 704 pumps are relatively high flow units with capacities up to 2000 l/h and 2 bar for industrial applications - typi- cally the food, pharmaceutical and chemical process indus- tries. The driven-roller pump- heads extend tube life and provide smooth low-pulse flows.
The pumps incorporate sev- eral safety features including a magnetically switched guard/ track which stops the pump if removed, and tool-lockable track setting knobs to prevent accidental adjustments being made to the tube occlusion.
The auto control 704U/R, switches instantly between manual and analogue control.

Vibration-free air operated stub pump
Tecalemit has launched a new 1:l low pressure transfer pump for efficient and controlled transfer of fluids from bulk storage containers in industrial environments or workshops.
The TEC-Millennium pump provides free-flow delivery of up to 50 l/h and can be used with most fluids, including oils, solvents and anti-freeze.
The pump has a smooth, double-action mechanical
stroke of 98 mm, with a 50 mm bore; it is vibration free, and operates quietly, due to the valve gear design and dynamic
balance. A non-return valve prevents flow-back during in- stant start up.
Versatility is built-in. The suction tube adapter can accept 38 mm bore plastic or rubber hose or a rigid pipe and the unit is suitable for fixing on a 2 in BSP bushing. It is designed for standard drums of up to 200 1 capacity and containers up to 6 ft deep.
The TEC-Millennium incor- porates a snap-action change- over valve so that it will not stall in low speed operation; it has a heavy duty zinc-plated body and is durable enough to withstand the rigours of life in industrial applications.
Extensive laboratory tests have been carried out on the pump to improve on durability: from these tests it has been

estimated that on a continuous pump in cycle, the life of the pump would be approximately 18 years.

Upgradeable pumpheads launched
Watson-Marlow has introduced the 313F/D fixed speed and 313S/D variable speed pumps which can meet immediate re- quirements but then be up- graded for additional pumping channels and auto-control.
Based around either the 313D three roller pumphead for maximum flow rate, or the 314D four roller pumphead for maximum pulsation, the pumps feature flip-top tube loading;

The maximum flow rate of the new 13 pumps is 2000 ml/ min at 400 rpm and pumpheads can be extended for multi- channel pumping in up to six

channels by simply adding snap-fit extension pumpheads.
The 313F/D fixed speed pump has electronic speed se- lection and is available with two maximum speeds switchable to lower speeds - 50/5 rpm and 400/200 r-pm. The 313 S/D is variable speed and has a 2O:l manual speed control ratio. Customers with future require- ments for analogue auto-con- trol, can purchase a plug-in 4- 20 mA or 0-IOV control card to upgrade their 313S/D to a 313U/D pump.

Teflon/PFA mag- drive pump
Ansimag has developed a KM- series horizontal magnetic drive pump.
The casing and impeller con- sist of Teflon@/PFA flouroplas- tic a mechanically soft, corrosion resistant material. Ansimag moulds this material in a metal cover and fibre composite in order to provide better pressure and pipe load resistance. Silicon carbide is used for the shaft and bushing for chemical resistance.
The pump achieves capaci- ties of 100 gpm and 100 ft head with a 5 hp motor. The 1% in suction and 1 in discharge ports have universal ANSI/ISO/JIS standard flanges.
