Calibration pots Prochem Calipots are used to confirm correct dosing rates from system dosing pumps. The Calipot is normally filled to a set level. The dosing pumps are then fed from it for a pre-set period – usually one minute or more. Next, the pumping rate is then checked against the time-calculated flow rate. Calipots are normally a permanent part…
Diaphragm seals Prochem diaphragm seals (or gauge isolators) are designed to enable standard construction pressure gauges and switches to be used on process lines carrying corrosive chemicals or sludges which would otherwise corrode or clog the sensing instruments. They operate by hydraulically isolating the pressure gauge or switch from the process stream via a diaphragm or sleeve.
Injection and sample lances Injection lances (or fittings) are generally used within dosing systems as a means of introducing chemicals into main pipeline streams. Sample lances are used to extract samples for quality monitoring. Prochem manufactures a wide range of both withdrawable and fixed fittings. Fixed fittings are installed semi-permanently and can only be removed with the main de-pressurised. On…
Pinch valves Prochem pinch valves are probably the simplest form of on/off or flow control valves available. They are suitable for handling a wide range of solids, sludges, and liquids. The valves are of extremely simple construction with only two major components – a flexible elastomeric sleeve contained within an annular body casing. The wearing component count is limited to…
Pressure loading valves The 1100 Series valves are designed specifically for the dosing industry. Offering exceptional reliability, flexibility and safety, they meet the needs of dosing pump manufacturers, dosing system builders and end users alike.
Pressure relief valves The 1100 Series valves are designed specifically for the dosing industry. Offering exceptional reliability, flexibility and safety, they meet the needs of dosing pump manufacturers, dosing system builders and end users alike
Pulsation dampers Designed to meet the needs of dosing pump manufacturers, dosing system builders and end users, Prochem pulsation dampers provide a simple, inexpensive and reliable means of stabilising flows and pressures whilst reducing pipework vibrations.
Suction demand valves The Series 2100 suction demand valve (SDV) is designed specifically for the dosing industry to hydraulically isolate a metering pump from its bulk supply tank to prevent variations in suction pressure and hence pump accuracy due to rising and falling tank liquid levels. By improving the dosing pump’s accuracy the valves provide two savings – first, by…
