The DLX range of pumps is a proven PTFE diaphragm type Solenoid Metering Pump that distinguishes itself with having a wide range of control options. Since its launch, the DLX pump range has given proven reliability and quality. It is the ideal solution for many chemical dosing applications where the moderate flow rate is required with counter pressures up to 20 Bar (290 PSI).

Key Features:
Pump Body Construction of Anti-acids mica-filled reinforced polypropylene.
Excellent water resistant for tough applications. Pump protection: IP65.
Either wall (DLX) or foot mount (DLXB) installations options available.
Liquid low-level option available to prevent loss of prime.
Flashing led showing pump’s stroke frequency.
Manual air bleeds polypropylene head for safe & easy priming with the durable leak-free bleed valve assembly.
Diaphragms are of superior construction, robust PTFE machined part not bonded composite layers, for optimum flexibility and long durability.
A wide variety of chemicals can be pumped due to different liquid end materials include glass-filled polypropylene (GFPPL), PVC, Polyvinylidene Fluoride (PVDF), PTFE, Plexiglas and 316SS. Valves and sealing in FPM (Viton), EPDM (Dutral), Nitryl, Silicone, ceramic and alloys.
Immediate installation and start-up, included as standard accessories with all models are an injection/back pressure valve assembly and a foot valve/strainer assembly, including discharge, suction and bleeding tubing.
Safe and easy priming and valve maintenance, included as a standard accessory is a bleed valve assembly, including return tubing (available only on those models with manual air bleed head).
Control panel protection assured by an adhesive polyester film, weather-proof and resisting UV light.
The silent version available upon request.
The products are manufactured according to CE regulation.
Standard power supply (fluctuations not to exceed ±10%): 230-240 V a.c.50-60 Hz single phase.
Optional power supply (fluctuations not to exceed ±10%): 110 V a.c. 50-60 Hz single phase. 48V a.c, 24V a.c/d.c., 12V d.c.
Overvoltage cat. II. Environmental Conditions: IP65 protection, altitude up to 2000m, ambient temperature 5°C to 40°C, maximum relative humidity 80% for temperatures up to 31°C decreasing linearly to 50% relative humidity at 40°C.


The DLX-DLXB CC/M metering pumps are activated by a PTFE diaphragm mounted on a piston of an electromagnet. 

When the piston of the electromagnet is energized, a pressure is produced in the pump head creating an expulsion of liquid from the discharge valve. After each pump pulse is finished a spring returns the piston back to the initial position, enabling a recall of liquid through the suction valve.

The operation is simple and the pump does not need lubrication, therefore maintenance is reduced almost to zero.

The DLX CC/M dosing pump is a micro-controlled unit suitable for operation in proportion to a "mA" input signal. Connected to a transmitter/indicator instrument or other devices which supplies a modulated current signal from 0 to 20 mA, the pump pulse frequency will be proportional to the mA signal received: higher the signal higher the pump flow or vice versa.

Manual flow control is available as an override. With level switch connection for auto-stop when the chemical level is low (level switch supplied as an option).

100% corresponds to the maximum stroke frequency, i.e. 120 strokes/min. Stroking rate gives a very high rate of reproducible metering accuracy.

The flow rate of the pump will depend on the counter pressure in the discharge line (please check flow vs. pressure diaphragm) and on the physical properties of the chemical being dosed. As a general rule, the pump flow rate will be higher if there is a lower is the counter pressure.​
