Pumps with Explosion Proof Motors
GOOD IN MOVIES.
NOT AT YOUR FACILITY.
KNF corrosion-resistant process industry pumps with explosion-proof motors offer safe solutions for handling aggressive gas or liquid media. KNF gas and liquid diaphragm pumps offer high performance and long service life during continuous, heavy-duty operation.
Diaphragm Gas Pumps and Compressors for Industrial Processes
KNF process diaphragm pumps, in several series, can achieve flows up to 300 L/min, vacuums to 29.86 in. Hg, and pressures to 176 psig, depending on model. All process pumps are designed to minimize power requirements and reduce costs, operate oil-free (to eliminate media contamination and maintenance), run without sliding seals, and incorporate precision ball bearings for optimized reliability.
Users may choose from 3-types of head configurations:
~ single-stage for moderate performance
~ two-stage for deeper vacuum
~ parallel-head for higher flow
These head configuration options, in addition to various combinations of materials and coatings, allow each customer to realize application-specific benefits. KNF also offers gas process industry pump models which are ATEX-compliant and certified in accordance with the 2014/34/EU directive on equipment and protective systems.
Shown here is the UN 035.3 STI EX pump, manufactured in the KNF USA production center.
Diaphragm Liquid Pumps for Industrial Processes
Our liquid handling diaphragm pumps are simple in design, durable, and perform their function without the need for flexible tubing or compressed air with their associated drawbacks. These liquid pumps are excellent for either vacuum or pressure applications. They are ideal for low viscosity liquids and can be run dry continuously, without degradation and under the most severe operating conditions without external leakage.
KNF NF 1.300 and NF 1.600 series liquid pumps offer safe transfer of explosive and hazardous liquids for chemical processing, petrochemical refining, and safety-critical applications. Self-priming up to 10 ft H2O, the pumps boast a pressure of 88 psig, flow rates up to 6 L/min, and are powered by 115/230V 60Hz single phase, UL and CSA approved motors. Contamination and maintenance-free, both models are available in corrosion-resistant versions.
