DLX dosing pumps

DLX solenoidal diaphragm dosing pumps

DLX Solenoidal Diaphragm Metering Pumps

  • Productivity: from 1 ÷ 20 l/hr.
  • Pressure: up to 20 bar.

DLX Solenoidal Diaphragm Metering Pumps is the most versatile series with the PVDF fluoroplast head. The high chemical resistance of the pump materials allows the use of virtually any reagent for dosing. DLX solenoid pumps can be made as with analog , and in microprocessor control . Pump housings made of plastic protected against acid vapor. The control panel is protected from ultraviolet radiation with a special film. Protection against dust and moisture IP 65. The standard height of the self-priming pump for all models is 2 meters.

DLX dosing pumps mounted vertically, wall mount . A special version of the DLXB comes with a bracket for mounting on a horizontal surface. DLXB dosing pumps cost 20 euros more than a DLX pump.

Performance control for the DLX series is done by changing the number of pulses per minute. However, for the DLXB variant, an additional R/C cap is provided, which allows you to change the stroke length of the piston for more accurate dosing at low flow rates. The cost of such a cover is 60 euros.

Operating principle of the DLX metering pump

The principle of operation of the metering pump is as follows: a Teflon membrane is attached to the piston (plunger), which is actuated by the action of a constant electromagnetic field of the solenoid. When the piston moves forward (under the influence of an electromagnetic field), pressure is created on the pump head, and fluid is ejected through the relief valve. After exposure to the electromagnetic field, the piston returns to its original position with the help of a spring, and fluid is automatically drawn through the intake valve.

The principle of operation is very simple, while the pump does not require lubrication, which reduces the maintenance process to almost zero.
Materials used for the manufacture of pumps make it possible to dispense aggressive liquids.

Various DLX Series Pumps

The DLX metering pump range consists of 8 different versions.

MA/AD is the simplest manual pump. The only analogue pump in the DLX line. It has a double dosing scale in the ranges of 10-100% and 2-20% (for more accurate dosing of small volumes). The only DLX line pump that doesn't support a level sensor.

MA/MB - dosing pump with microprocessor control. Instead of the rotary knob of the potentiometer, the performance is set on the digital display in 1% increments.

CC/M - proportional dosing pump from external 4-20 mA signals. Manual dosing is also possible (similar to MA/AD). Supports reverse dosing.

VFT/MBB - proportional metering pump from an external pulse flow meter. For each pulse, the pump gives a certain portion of the reagent (the portion is set in the modes 1xN, 1: N, 1xN (M - with a parameter in the memory), where N is the number of incoming pulses). It may also work in manual dosing mode.

MF/M is the most advanced proportional metering pump that supports both a pulsed flow meter and 4-20 mA signals. The only DLX pump that has a two-line LCD with backlight (all other microprocessor pumps have a single-line display with no backlight). Also has a timer, buzzer, clock, relay alarm output. In addition to the level sensor, the pump supports a flow sensor (not included).

PH-RX/MBB - proportional metering pump with integrated pH/RedOx controller. The user determines which parameter the pump controls. pH is measured in the range from 0 to 14, and RedOx (redox potential) from -1000 to +1400 mV (millivolts). The pump runs in constant or proportional mode. On delay function. In addition to the level sensor, the pump supports a flow sensor (not included).

PH-RX-CL/M is a version similar to the previous one, but in addition to the pH/RedOx controller, a chlorine controller is also added (measuring range 0-20 ppm or mg/l). 4-20 mA output. Relay alarm output. Temperature compensation in automatic mode (when installing the appropriate PT100 sensor). In addition to the level sensor, the pump supports a flow sensor (not included).

CD/M - proportional metering pump with controller CD (conductivity). Electrical conductivity is measured in the range from 0 to 1000, or from 0 to 10,000 µS (micro-sensor or. Micro S). 4-20 mA output.
