Severn Trent Services has developed an autonomous duty/standby booster pump skid system with PID pressure control

Severn Trent Services has developed an autonomous duty/standby booster pump skid system with PID pressure control.
The design of the autonomous duty/standby booster pump from Severn Trent Services enables it to maintain constant water pressure under varying flow demand requirements when used in ClorTec® on-site sodium hypochlorite generating systems.
Low inlet water pressure, pressure losses through a distribution [...]

Dolomite has introduced the Mitos P pump

Dolomite has introduced the Mitos P pump, which provides a pulseless liquid flow using a pressure-driven pumping mechanism.
The Mitos P pump is suitable for microfluidic systems, where highly stable flow is required in applications such as droplet formation.
The pulseless liquid flow pump from Dolomite operates over a pressure range of 0-10 bar and is suitable for [...]

Smedegaard has released its new WallPress Whisper range of pressurisation pumping systems

Smedegaard has released its new WallPress Whisper range of pressurisation pumping systems.
According to Smedegaard, the system is “whisper-quiet” in operation, with a noise level less than that of competitor models.
The Whisper range is designed to provide a minimum system pressure requirement. It incorporates a digital microprocessor Control Module which delivers system diagnostics, high and low pressure [...]

ProMinent has developed the TriPower MF a process pump with a small footprint

ProMinent has developed the TriPower MF, a process pump with a small footprint. It has an integrated gearbox which helps make the design more compact.
The TriPower MF oscillating displacement pump has a fixed stroke which delivers up to 38 m3/h at pressures of up to 400 bar. The TriPower MF pump is resistant to aggressive, corrosive, [...]

Compact vacuum pump for solar cells

Compact vacuum pump for solar cells

Edwards has introduced iXL500, the first in a line of dry vacuum pumps designed for load lock applications in solar cell and flat panel display manufacturing.
According to Mike Allison, MD of the solar, semiconductor and flat panel display divisions at Edwards, the iXL 500 offers up to 60% improvement in cost of ownership compared to [...]

Larger air valve for motor vane pumps

Larger air valve for motor vane pumps

Blackmer has introduced a 3 in configuration of the piston air valve used on its TX/TXD Series of sliding vane pumps.
The piston air valve has become the standard air-valve option on Blackmer’s 3 in TX/TXD pumps, in place of the diaphragm air valve.

Blackmer claims that piston air valves provide a much longer service life and [...]

Pump can solve low-flow problems

Griswold Pump Co has introduced a new line of low-flow ANSI pumps designed for the severe conditions found in some process and transfer applications.
The Model 811LF pump incorporates a circular concentric volute casing in conjunction with a radial vane impeller making flow capacities down to 4 gpm with heads up to 920 ft possible. [...]

Wilden pumps ATEX certified for use in explosive atmospheres

Dover Corporation’s Pump Solutions Group has launched its Wilden Advanced and Original X Series Metal and Plastic air-operated double-diaphragm (AODD) pumps which comply with the ATEX 95 directive for explosive atmospheres.
The ATEX directive consists of two European Union directives that describe what equipment is allowed in an explosive atmosphere. The Wilden metallic X Series pumps comply [...]
