Wilden has launched the 76 mm T1510 Advanced Brahma metal pump incorporating the company’s the traditional Turbo-Flo air distribution system (ADS). The pump has a top inlet and bottom discharge, and uses flap valve technology to allow the passage of large solids. The bottom discharge and large flow-through design prevents settled solids from damaging pump internals upon restart.

The Turbo-Flo ADS is reportedly easy to maintain, externally serviceable and is completely submersible, allowing the Brahma

to be used in harsh environments such as mine dewatering and sludge and slurry applications, the company says.

The T1510 Brahma pump is constructed of rugged aluminium or ductile iron wetted components and aluminium and brass ADS materials. This new pump is available with Buna-N or neoprene elastomers.

It has a maximum flow rate 977 lpm (258 gpm), maximum solids passage of 76 mm and maximum operating pressure of8.6 bar (125 psig).

Wilden launches metal pump

UK-based Busch Ltd has launched a new F version of its R 5 rotary vane vacuum pump, which the company says is designed for continuous use in numerous applications.

New features of the F model include an improved ultimate end pressure of 0.1mbar, increased suction capacity at low pressure and reduced model

variants. Busch says the compact design of the R 5 makes it easy to maintain and service, while being ideal for use in situations where space is limited.

The pump is environmentally friendly and includes air cooling, internal oil recirculation, integral oil mist separator for oil free exhaust air, low vibration and low noise level.

Pump head kit from Varna

Varna has launched a pump head and adaptor kit available in AC and DC voltages.

The C Face pump head and adaptor easily connects to C Face Motors and the adaptor connects to any 56, 143 or 145 C Face Motor in minutes, the company says. This line of pump heads has been developed with a sliding vane design that has lower power consumption than gear or piston pumps. The pump kit is constructed of cast iron, steel and aluminum and is efficient in non-corrosive, non-sanitary applications.

The C Face pump head and adaptor kit operate at flow rates of 42 to 3 gpm depending on motor RPM and the use of variable speed reducers. The kit is built to handle oil temperatures of 28°F.

Bell & Gossett unveils bypass valve

A differential bypass (DB) valve designed to control excess flow in hydronic systems has been introduced by Bell & Gossett.

When there is a reduction in demand, the new valve acts as a bypass while ensuring adequate flow to the remaining open circuits, the company says. It is designed to be used in systems where heating loads may be excluded from the circuit as zone valves close and can help reduce velocity noise caused by excess flow through the circuits, while maintaining the pump head at a constant value.

Developed for hydronic systems utilizing zone valves, the new valve has an all-brass body with non-ferrous internals and is available in horizontal or vertical installation with a ¾ inch connection. Its maximum working pressure is 150 PSIG and maximum operating temperature is 230°F (110°C).
