DLX VFT/MBB

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.

                       Characteristics

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

 

When the piston of the electromagnet is attracted, a pressure is produced in the pump body with an expulsion of liquid from the discharge valve. After each pump pulse is finished a spring brings the piston back to the initial position, with a recall of liquid through the suction valve.

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

The DLX VFT/MBB dosing pump is a micro-controlled unit suitable for operation in proportion free tension (reed) contact normally generated by a water meter.

DLX VFT/MBB has proportional/manual modes: Manual mode; Pulse multiplier with memory (1xn-M); Pulse multiplier (1xn); Pulse divider (1:n).

Output service relay related to low-level chemical input.

PRIMING (100% flow) is possible in all meter modes by pressing and holding simultaneously right and left arrows.

The dosing pump is supplied with a level control setting. When the chemical tank is empty, on display it appears AL1 and the pump goes in standby. The level of control has 5 seconds of delay.

Proportional dosing via a contact water meter represents a regulated form of losing control. It is used as a chemical feed in the water supply pipes of simple industrial processes and private applications. 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 to dose. As a general rule higher will be the pump flow rate lower is the counter pressure the pump will face.
