Blowers & Exhausters

Description Volumetric Blower The Volumetric Blower is an "oil-free" lobe pump for air or non aggressive/non explosive gases suitable to operate with a maximum backpressure of 1000 mbar at discharge, and a maximum vacuum of -500 mbar, withing the allowable temperature limits. AC Exhauster The Air Cooled (AC) Exhauster is an "oil free" rotary lobe pump for air or non aggressive/non explosive gases suitable to operate with a maximum vacuum of -0,85 mbar, within the allowable temperature limits. Technical Details The three-lobe rotor is the evolution of the classic bi-lobe design, shaped like an "eight". This design ensures higher bending stiffness, and lower pulsation amplitude that consequently reduces vibration. The economic advantage in the bearing life is appreciable. The compressor noise is remarkably decreased as well. The synchro-gears are case hardened and tempered. Gears are accurately ground to ensure optimal timing. The "long addendum" involute design gives maximum efficiency with virtually silent mechanical operation. Pump's body, sump and covers are assembled with flat gasket to ensure maximum tightness. This results in increased reliability which decreases mainenance costs. The sealing of the rotors is achieved with labyrinth seals, which do not make contact and therefore do not create friction. This is ideal for the rotor's high rotation speed. This solution saves money due to the decrease in energy dissipation and absence of any other expensive cooling system.

Multi-Stage and Self-Priming Pumps

pump, travaini pumps, multistage, self-priming

Description Multistage centrifugal pumps with closed impellers. Technical Details The impellers are in series so that the head increases as the liquid being pumped is transferred from each impeller. The axial thrusts are balanced by balancing blades on the back of the impeller. The remaining thrust forces are absorbed by the heavy duty single ball bearing at the non-drive end and angular bearings at the drive end. For pump designs that have two external bearings, a pressure pipe is provided to relieve pressures in the seal area from the discharge side of the pump to the suction side. The TMA pump design uses the latest foundry technologies. This allows for one piece components which effectively increases pump efficiencies, at the same time, reducing the weight of the pump without sacrifing the overall strenght and durability. Capacity from 1 to 45 m3/h and head from 4 to 40 bar. Special Constructions For the smaller TMA 31 & 32 series a close coupled design is available where space is limited. This design also eliminates any concerns for misalignment, which will enhance the pump’s performance and extend the overall life of the pump.

Description OilSys is an engineered system for the installation of a total recirculation liquid-ring vacuum pump that uses mineral oil (or similar) as operating liquid, in order to guarantee maximum flow rate and vacuum performance higher than those allowed by water. It is composed of: Liquid-ring vacuum pump Separator tank which also works as a frame Heat exchanger Oil demister filter Functioning The gas handled by the vacuum pump is discharged with some of the service oil into the special frame which acts as gas/oil separator and allows separation from the oil of any evacuated condensables. The oil is returned to the vacuum pump by means of a circulation pump after being cooled through the heat exchanger. The gas is vented after being filtered of any oil through the specially engineered oil demister filter. A pressure gauge at the filter housing will indicate over pressure when the oil demister filter is plugged and needs replacement.

Description Single-stage centrifugal pumps with closed impeller for thermal oil. Technical Details TCD pump series are specifically designed to handle thermal fluids up to 320˚C without special cooling systems. In the active cooling version "XT" it is possible to pump diathermic fluids up to a temperature of 365 °C. 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 TCH series 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”. 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 up to 10 bar. Special Constructions TCD/SP TCD/SP pump series 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.
