BOXER Diaphragm Pumps

TECHNICAL CHARACTERISTICS:

construction materials: PP, PVDF, ECTFE, ALU, and AISI 316;
used in potentially-explosive environment (ATEX certification, 1,2 zones);
applicable to severe conditions and high-humidity environment;
dry operation is allowed;
dry start up;
the energy of compressed air without using any particles of lubricant acts as drive;
adjustable performance and operating suction head;
fine tuning of motor speed at constant pressure;
double-manifold option (two inlet and two outlet openings);
three inlet and three outlet nozzles;
diaphragm pumps for heavy and viscous products.

Construction Materials


PP (Polypropylene)	ECTFE (Teflon)	Alu (Aluminum)	AISI 316 (Stainless steel)

Diaphragm pumps operated by compressed air energy Advantages: Easy construction: no motor, reducer, and rotating parts. Compressed air energy is a drive; there is no spark formation; absolute safety when working with flammable liquids. Compact size and small weight. Universal application: pumping water, pumping viscous liquids, pumping liquids containing solid particles ranging from 12 to 15 mm in diameter. No seals and bearings, thus no leakages and main parts wear. Easy flow rate adjustment. No lubrication and maintenance required during the pump operation
Description
	Diaphragm pumps consist of a centered-coaxial pneumatic device with the new generation diaphragms fitted to the shaft. There are also valves and corresponding seats of the product inlet and outlet nozzles installed at both ends of the pump housing.
	A - ball valves B – pump chamber C – diaphragms D - inlet nozzle E – outlet nozzle F – pneumatic motor
The Way it Works
The compressed air generates from the pneumatic exchanger (А) through one of the two diaphragms. It compresses and pushes the product into the outlet nozzle (В). Decreased pressure, which is created by an opposite situated diaphragm (C), integrated with a coaxial shaft, results the fluid intake. After each stroke, the pneumatic exchanger diverts the compressed air to the opposing diaphragm, and the cycle repeats itself.
