Overall dimensions and performances are in accordance to standards ISO 2858/DIN 24256. Materials 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/UNI EN 12756) with every installation option per API requirements. Pump casing and seal housing can be provided with heating or cooling chambers, as needed. Units up to 30 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. From the TCH series have derived series TCT, TCA and TCD that are designed for very specific pumping applications; all these series utilise many common components. Mechanical Seal TCH pump series and derived series can be fitted with any type of mechanical seal that is unified to the ISO 3069/UNI EN 12756 standards. Single mechanical seals, double mechanical seals in tandem or back to back arrangements can be fitted with flushing systems to API standards. The pump bearing frame offers versatility and plenty of space to also allow fitting special types of mechanical seals that may not have unified dimensions, i.e.: cartridge type seals Materials TCH pumps have many material solutions, starting from cast iron and stainless steel iron up to SAF and Hastelloy.

Description TCD pump series (see cross section below) are specifically designed to handle thermal fluids up to 320˚C without special cooling systems. The heat from the pumped product is greatly blocked by special “heat barrier” chamber located between the pump casing and the impeller. The bearing frame has been especially designed with cooling fins to effectively dissipate the heat coming from the pump casing so that standard, simple and single mechanical seal can be safely used. The rotor is supported with oversized ball bearings of the C3 series that are lubricated with oil of medium viscosity. Pump casings and impellers are the same as for pump series TCH smaller two frames. Materials of construction are Ductile iron or Stainless steel AISI 316. For the latter construction it is possible to have a special seal arrangement “SP” (see page at side). Pump dimensions and characteristics are in accordance to ISO 2858/DIN 24256 standards and are the same as for the correspondent models from the TCH series. Capacity up to 350 m3 /h and head to 10 bar. Special Executions TCD/SP TCD/SP pump series (see cross section below) has been especially designed to handle vegetable oils. The design varies from the standard TCD series only in the mechanical seal area; an intermediate cover has been added beyond the mechanical seal. This intermediate cover should be connected to a reservoir containing oil compatible with the pumped fluid. This device avoids that, in case of mechanical seal breakdown, air can enter into the pump irreparably oxidating the pumped oil or that oil of bearings enter into pumping circuit or vice versa.

Liquid Ring Vacuum Pumps
Description The TRVX series of single-stage liquid ring vacuum pumps introduces an innovative project, new performance, greater reliability and is the result of Pompetravaini's experience and feedbacks from end users. The result is a milestone in the design and production of liquid ring vacuum pumps, offering tangible benefits to users. Technical details The new hydraulic profile allows a performance increase over 10% than the traditional liquid ring vacuum pump designs. Increases the efficiency and operational cost savings all over the entire pump life. The pump weight is average 30% less compared with the traditional liquid ring vacuum pump designs with compact supporting components dimensions. This advantage allows installation and transportation costs saving Compact dimensions and volume (L x W x H) 50% less compared with the traditional liquid ring vacuum pump designs. Optimization of factory or plant installation spaces and related costs saving. Single and direct service liquid connection. Easy pump fitting without the use of complicate piping. This ensures a fast and economic pump installation Central body impeller housing with integrated suction and discharge manifolds with compact overall dimensions. This feature reduces pump components and increases robustness. The maintenance and assembly time and costs saving result to be greatly advantaged. The suction and discharge port plates are always in stainless steel allowing a greater reliability trough the time and ensuring stable performances. They never require to be replaced during ordinary maintenance reducing down the spare parts cost.

Description The TRMX series is the transfer of all the TRVX series basic concepts on the monoblock pumps production. The result is an economical pump with outstanding performance and reliability. The new hydraulic profile design allows a performance increase from 10% to 20% compared with previous series. This increases the efficiency and operational cost savings all over the entire pump life. Compared with the previous TRMB series, the TRMX is 10% lighter. The volume is 10-20% smaller. These two features permit fast and less expensive installations. Maximum flexibility for handling the sealing liquid. In std. condition the TRMX series requires up to 40% less sealing fluid flow compared with the previous TRMB series, ensuring a big saving in the operating cost. In the applications where is required the possibility to aspirate big sealing liquid flow, pumps are supplied with enhanced higher sealing liquid flow capability Inox port plate with laser cut port profiles. This solution make the port plate free from wear and the laser cut ports guarantee the execution of the best performing designed profiles. Very noticeable the increase of the pump working economy Innovative anti-cavitation system derived from the TRVX series. The injection port is located very close to the suction port improving the highest operational vacuum level and guarantee higher efficiency all over the pump vacuum range. With this solution the pump operational cost is reduced in a sensible way.
