The PKX is a PTFE diaphragm type Solenoid Metering Pump that distinguishes itself for its simplicity of use. It has proven reliability and quality and due to its compact design and versatility the PKX series is the ideal solution for many chemical dosing application where the moderate flow rate is required with counter pressures up to 6 bar (87 psi).
Anti-acids mica-filled reinforced polypropylene material of enclosure.
Excellent water resistant for tough applications. Pump protection: IP65.
Both wall or foot installations using the universal support bracket supplied with the pumps
Reduced dimensions for effective use of space in a dosing rig, ideal for OEM applications.
Liquid low-level option available to prevent loss of prime.
Flashing led showing pump’s stroke frequency.
Robust potentiometer for flow rate setting, IP 65 ON/OFF switch.
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 rays.
The silent version available upon request.
The products are manufactured according to CE regulation.

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
he PKX FT/A metering pump is 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.
PKX FT/A metering pump is an analogical dosing pump designed to Dosing proportionally to incoming free tension contacts (normally generated by a water meter).
Two optional features: volumetric proportional (1injection per 1 impulse) or volumetric with a timer (programmable injection time per each impulse received - timer range: 0-60 sec). Level control setting included (supplied without probe). 120 strokes/min maximum stroking rate.
Power LED "green"
Pulse LED "red"
Level alarm LED "yellow"
Adjustment knob of the percentage of time
Pump flow rate can be controlled manually by setting the pump pulse rate by means of the knob.
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.
