Because these pumps are run by an electronic magnet, the complexity of a motor driven technology is unnecessary. The vibrating diaphragm pumps run completely frictionless. The outcome is an extremely high durability – ideal for continuous operations. Low pressure up to 0.3 bar, high volume performances up to 10 l/min and a prominent operation smoothness – these characteristics are ideal for stationary analysis machines. In additon, there is an optimal cost/performance ratio: ideal for mass productions. For different specific applications, the pumps of the construction series SA are available as: AC Model – for operations on AC voltage. DC Model – for operations on DC voltage. DV Model – to optimize pressure performance. VD Model – to optimize vacuum performance. Schwarzer Precision - over 30 years experience in gas and liquid pumps: that's what we are all about. Evidence is in the extensive range of products from diaphragm pumps, to vane pumps, piston pumps and micro pumps to miniature diaphragm compressors.
