4Pages

The new pump series TCH and derived series of the same family, reflect the design guidelines given by ISO 5199 class II standards. These norms provide for the introduction of new and severe manufacturing standards applicable to the pumps manufactured according to ISO 2858 standards in order to get an ideal product for the heaviest uses, especially in the petrochemical industry, following the example of API standards. These pumps are also the results of Pompetravainis continuous research and developmen t, of the extensive experience acquired over many years with the previous series MCU-CH applied in numerous installations and fields. Finally we believe these pumps reflect the many suggestions and opinions received from our vast clientele and users. > All o ur production is guaranteed by certified quality system according to ISO 9001 standards. The TCH pump series is an extremely improved product for: > ? Toughness > ? Efficiency > ? Reliability > ? Safety > ? Durability > ? Lower operating costs The manufacturing program includes three bearing frame sizes of the ғBack pull-out type; the pump casing is of the spiral type with axial suction flange; the impeller is of the radial type with overhang mounting. > ? Handling clean or slightly contaminated liquids, hot, superheated, acidic and caustic in chemical industry, petrochemical, pharmaceutical, food, pulp and paper, environmental, steel, textile, etc. > ? Capacity up to 500 m > 3 /h and heads to 16 bar. > ? Overall dimensions and performances are in accordance to standards ISO 2858/DIN 24256. > ? Mate rials of construction are numerous, from cast iron to hastelloys. > ? High hydraulic efficiencies and low NPSH requirements. > ? Shaft sealing by packed stuffing box, single or double mechanical seals (ISO 3069/DIN 24960) with every installation option per API req > ? Pump casing and seal housing can be provided with heating or cooling chambers, as needed. > ? Units up to 22 kW size can be close coupled, with the addition of a support lantern, to motors with B5 flange. This monoblock design offers great alignment advantages, simplicity of assembly and guarantee of perfect alignment even after transportation. >
