DULCOFLEX Series Peristaltic Metering Pumps

DULCOFLEX peristaltic pumps feed outgassing and abrasive media from 10 ml/h to 410 l/h at up to 8 bar. The valveless fluid path prevents clogging and media backflow. Quick-release hose clamping shortens scheduled maintenance downtime.

Dosing output from 10 ml/h up to 410 l/h at back pressure reaching 8 bar
Valveless direct peristaltic mechanism eliminating clogging and backflow
Heavy-duty pump tubing available in Santoprene, Norprene, and EPDM
Patented quick hose exchange system without piping disassembly

Bello Zon Chlorine Dioxide Generation and Disinfection Systems

Bello Zon systems generate chlorine dioxide from 1 to 2,000 g/h ClO2 for industrial water disinfection. Synthesis from diluted precursors avoids free chlorine formation. The plants eliminate microbial biofilm across water distribution loops.

Chlorine dioxide generation capacity from 1 g/h up to 2,000 g/h ClO2
Acid-chlorite synthesis route delivering over 95% stoichiometric yield
Integrated PVDF reactor vessel with overpressure relief and leak sensor
Automated operation for municipal waterworks and beverage facilities

DULCOMETER Controllers and DULCOTEST Analytical Sensors

DULCOMETER diaLog DACb controllers monitor pH, ORP, chlorine, and conductivity via DULCOTEST sensors. The instrumentation provides closed-loop PID control of metering pumps. Process values transmit to plant automation networks via Modbus and Profibus.

Multi-parameter monitoring of pH, ORP, free chlorine, ozone, and conductivity
Individually configurable measurement channels on diaLog DACb controller
Continuous PT100/PT1000 temperature reading with automatic compensation
Direct closed-loop feedback control of dosing pumps via industrial buses

Positive Displacement Metering Fundamentals in ProMinent Pumps

ProMinent positive displacement metering pumps deliver continuous and stroke-synchronised chemical feed with volumetric accuracy within one percent. The equipment matrix encompasses gamma solenoid diaphragm units, Sigma motor-driven pumps, and Hydro hydraulic diaphragm systems.

An integrated digital microprocessor continuously profiles the diaphragm displacement curve against pipe back pressure, compensating for flow variations and eliminating airlocks without requiring supplementary in-line flow meters.

Kinematic Comparison Between Solenoid and Motor-Driven Metering Pumps

Solenoid metering pumps gamma/ X and gamma/ XL feature an electromagnetic drive designed for high-frequency low-volume dosing with electronic stroke adjustment.

The Sigma motor-driven platform utilises a mechanical worm gear mechanism delivering high volumetric throughput up to 1,040 l/h at discharge pressures up to 12 bar.

Both pump configurations utilise multi-layer Developan safety diaphragms equipped with optical sensors to detect diaphragm rupture before corrosive media can penetrate the drive housing.

Heavy-Duty Hydro API 675 Hydraulic Diaphragm Process Pumps

ProMinent Hydro series process pumps (Hydro/ 2, Hydro/ 3, and Hydro/ 4) are engineered in full compliance with API 675 technical requirements for oil, gas, and petrochemical production.

The hydraulic diaphragm coupling ensures balanced pressure across the PTFE diaphragm, delivering dependable operation at flow rates up to 1,506 l/h and pressures up to 100 bar.

An integral pressure relief valve with automatic hydraulic fluid replenishment safeguards the pump head against overpressure conditions.

Valveless DULCOFLEX Peristaltic Pumping for Abrasive Chemical Media

DULCOFLEX peristaltic pumps (models DF2a, DF4a, DFXa, and DFYa) meter outgassing, viscous, and abrasive chemical slurries without valve clogging. Fluid contact is entirely confined to the reinforced elastomer tube, preventing chemical attack on internal mechanical components.

The precision roller mechanism produces uniform tube compression, minimising discharge pulsation and extending hose life during continuous feeding of lime slurry, polymer flocculants, and activated carbon.

Bello Zon and DULCODES Water Disinfection Plant Engineering

On-site water disinfection infrastructure incorporates Bello Zon chlorine dioxide generation plants and DULCODES ultraviolet reactors.

Bello Zon systems synthesize pure chlorine dioxide solution from sodium chlorite and hydrochloric acid with reaction conversion exceeding 95 percent, providing enduring disinfection without forming carcinogenic trihalomethanes.

Complementary DULCODES LP UV systems deliver targeted germicidal irradiation, neutralizing pathogenic microorganisms without chemical residuals.

Online Analytical Instrumentation: DULCOMETER Controllers and DULCOTEST

Process water quality management relies on DULCOMETER diaLog DACb multi-parameter controllers connected to selective DULCOTEST electrochemical sensors. The analytical network continuously monitors free chlorine, chlorine dioxide, ozone, pH value, and electrolytic conductivity.

The controller executes closed-loop PID control to modulate dosing pump stroke rates, maintaining chemical balances while transmitting operating telemetry via Modbus RTU or Profibus DP protocols.
