The Kraissl Company is along-time manufacturer of heavy duty click picsimplex strainers/filters, duplex strainer/filters, transfer valves and pumps for protecting equipment in pipeline service.
Since 1926, The Kraissl Company has been an industry leader in the manufacture of heavy duty simplex and duplex strainers, filters, transfer valves, and oil transfer pumps.
Kraissl was the first to develop duplex 3-way (6-port) transfer valves with standardized port connections for external equipment. These tapered plug-type models were adapted from Kraissl's duplex strainer designs.
Our complete line of duplex three-way (6-port) transfer valves was developed specifically for use with two filters, two heat exchangers, two supply tanks or with other dual systems -- positive displacement oil transfer pumps and rotary air pumps are also our specialties.
all Kraissl products are manufactured in the U.S.A. to assure high quality workmanship and materials at affordable prices.
Kraissl Co. products are listed by Underwriters Laboratories (U.L.), Inc. and manufactured to stringent quality control specifications.
Models for fuel oil and flammable fluid service bear the Underwriters Laboratories (U.L.) label.
Kraissl strainers are manufactured in accordance with International Standard ASTM F-1199.
