Sodium hypochlorite creates gas locking and crystallisation in diaphragm pumps.
Flow rates and pressure changes fluctuate impacting metering accuracy. Diaphragm pumps are often set to ‘over-dose’ to ensure water quality is maintained. This increases chemical usage and secondary treatment to compensate.
Qdos 30 delivers predictable, accurate metering at variable pressure up to 7 bar (100 psi), even with fluctuating process conditions. Gas locking and crystallisation issues are eliminated.
Water pH influences the effectiveness of disinfection.
Metering alkalis such as Calcium Hydroxide creates issues with clogging and damage. Metering acids carries safety implications and can corrode pipework and equipment.
Qdos 30 metering pumps minimise pH ‘overshoot’. Suspended solids are handled with no risk of clogging, and the innovative ReNu pumphead ensures safe operation with built-in fluid recovery.
Accurate pH control is critical to ensure maximum yield.
However the toxicity of reagents such as sulphuric acid and cyanides are hazardous and can damage pumps.
ReNu pumphead technology ensures the safe metering of toxic chemicals. Fluid recovery and no-tools maintenance means an operator can quickly and safely change the pumphead. The process can be back up and running in minutes.
Chemicals used in cooling water treatment to prevent corrosion and scale formation affect cooling efficiency and impact operating costs.
A metering skid may contain five pumps, each with its own configuration and operating requirements. Qdos 30 delivers accurate flow, even at very low flow rates combined with high discharge pressure.
There are no valves in the flow path to wear, and the ReNu sealed pumphead ensures quick and safe pumphead replacement with no risk of leakage, giving you savings on skid ownership costs
Flocculants can cause clogging in diaphragm pumps, increasing maintenance and process down-time.
Environmental conditions such as temperature affect fluid viscosity also affect diaphragm pump performance.
Qdos 30 delivers accurate metering even with fl uctuating viscosity. There are no seals or valves in the flow path to clog or wear, meaning pump performance is never compromised.
