Exacta Series

Summary

Product Identification

The Exacta Series comprises plunger and mechanical diaphragm pumps with a spring return mechanism, designed for accurate dosage of chemical additives. These pumps are suitable for various applications, including water and wastewater treatment, pulp and paper, and food & beverage sectors.

Key features:

• Wet parts available in stainless steel or plastic materials.
• Stroke variation controlled by an eccentric shaft based on a spring return mechanism (aluminium housing).
• Equipped with a low-noise warm gear speed reducer.
• Driver can be mono or three-phase, in agreement with IEC standards.

Electrical

• Driver: Mono or three-phase, in agreement with IEC standards.
• Electric Servomotor (for stroke adjustment):
  • Power supply: 100-250 V, mono phase, 50 Hz
  • Protection rating: IP65
  • Feedback signal: 4÷20mA

Mechanical / Hydraulic

The pump flow rate can be adjusted by controlling the stroke variation through:

• Manual adjustment: With a grip handle and graded vernier.
• Electric servomotor: With a 4÷20mA signal and manual emergency adjuster, for automatic remote adjustment.
• Inverter: By regulating the speed of the motor, while maintaining manual/electric adjustment in the stroke length.

Accessories

• Safety valves
• Pulsation Dampers
• Back pressure valves
• Calibration pots
