We offer an extensive range of metering pumps for almost every situation where liquids have to be accurately metered or blended together. Our NOVADOS metering pumps comprise diaphragm and plunger pumps, with drives to accommodate single or multi-stream applications using horizontal or vertical confi gurations. Nearly all gear sizes in the NOVADOS series can be combined for process and metering pumps to achieve the required flow rate and pressure parameters. Manual or automatic control options for fl ow rate adjustment are available, with various liquid end materials and complemented by a variety of accessories to suit the process.These numerous possible combinations and variants enable bespoke solutions to be offered, which suit the characteristics of the metered liquid.
Typical application
Chemical industry, food and beverage production, household chemicals, energy industry, environmental protection, oil and gas, personal protection, petrochemical industry, pharmaceutical industry and biotechnology, paper and textile industry, water treatment.
Benefits
- Excellent dosing accuracy - accuracy of +/- 0.5% thanks to the use of special gears.
- Complete tightness - hermetically sealed pump design.
- Process optimisation - performance can be adapted to a wide range of production processes.
- Excellent flow control - variable stroke length allows independent flow rate adjustment for each pump element. Smooth flow for all pump stroke settings thanks to the special design of the inclined crankshaft.
- Adaptability - existing installations can be modified or expanded with additional pumps or automatic control.
- High operating efficiency - automation for higher production output.
- Variable speed drive - flow rate can be changed while maintaining constant mixing parameters.
- Multi-head system - many pumps with up to 12 heads are available. Individual head sizes allow pumps with a maximum flow rate of 0.4 l/h to 22,365 l/h to be selected.
- Designed for use in potentially explosive atmospheres - compliant with the ATEX directive.
