The BT-BTB BT PH-RX-MBB 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 BT-BTB pump range has given proven reliability and quality. It is the ideal solution for many chemical dosing applications where moderate flow rate BTB or high flow rate (BT) are required with counter pressures up to 20 Bar (290 PSI).
Either wall (BT) or foot mount (BTB) installations options available.
BTB - pump body construction of Anti-acids mica-filled reinforced polypropylene.
BT - pump body pump housing is constructed of cast Aluminium, protected by double coats of Epoxy paint.
Excellent water resistant for tough applications. Pump protection: IP65.
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.

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 BT-BTB pH-Rx-CL/M dosing 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.
