Bild vergrößernSchlauchpumpe DULCO®flex DF3a

The DULCO®flex DF3a peristaltic pump has been specifically developed for dosing fragrances in wellness facilities. This pump can be used wherever it is necessary to deliver fragrances in small quantities.

  • Capacity range 0.4 - 2.4 l/h, at 1.5 bar back pressure
  • Silent-running synchronous motor with four gear stages
  • External system control via contact and time interval input (button, door switch, motion detector …)
  • Cycle, operating and hose hours counter with hose change indicator
  • Intake function (continuous operation)
  • Three level inputs
  • Relay output for actuating solenoid valve (for dilution) or fan
  • Reproducible, infinitely variable time interval control – all time intervals can be changed independently and at any time for time-based dosing
  • Operation and control of two further DF2 fragrance pumps possible
  • Expandable hardware functions (additional pcb)
  • Sign-based user prompting and programming with four buttons for easy and safe operation
  • Straightforward installation ensures flexible retrofit and expansion in existing wellness facilities
  • Convenient, automatic dosing of up to three different fragrances
  • Programmable time intervals can be changed at any time. The currently set dosing intervals can be read off from a large two-line liquid crystal display
  • Economy mode for efficient operation: “Dosing only as required”
  • Hose change made easy by servicing friendly design

Accessories (10)

Accessorie Product details
Injection Valve

Used for generating pressure and preventing backflow.

Remember
Back Pressure Valve

Used to generate a constant back pressure for precise dosing and/or to protect against overdosing, or for dosing accuracy with an open discharge or a positive pressure on the suction side. Used with pulsation dampeners to produce low-pulsation dosing.

Remember
Foot valve

For connection at the end of the suction line. Used to create pressure and to prevent return flow. Important: Injection valves are not intended as completely sealed units.

Remember
Float Switch

Float switches enable problem-free and flexible integration of metering pumps into automatic control loops.

Remember
Suction Assembly

For ProMinent® solenoid pumps consisting of foot valve, adjustable retaining tube with screw connection and intake line.

Remember
Suction Lance

Consisting of foot valve, retaining tube and screw connection, intake hose.

Remember
Suction and discharge pipe

for metering pumps and accessories. We recommend using the original lines to ensure the mechanical connection in case of clamping ring fittings as well as compressive strength and chemical resistance. On request, food grade version is possible.

Remember
Control Cable

Control cables enable problem-free and flexible integration of metering pumps into automatic control loops.

Remember
Relief Valve

The relief valve protects all system components against damage due to pressure overload.

Remember
