What are the Key Features and Advantages of Trochoidal Lobe Pumps?
Excellent Suction Capability
Pulsation Free Flow
Compact and Lightweight Design
Easy In Place Maintenance
Reliable High Speed Operation
High Pumping Efficiency
Precision machined components guarantee high volumetric efficiency and overall efficiency
What are the advantages of TUSHACO RTBP Series Over Standard RT Pumps?
Compact Installation
Close coupled monoblock design eliminates the need for separate base frames, reducing installation space.
Flexible Mounting
Can be installed in either horizontal or vertical positions.
Simple Foundation Requirements
No elaborate foundation is required, making installation easier.
No Coupling or Alignment Issues
Direct motor mounting eliminates couplings and associated shaft alignment problems
Easy Dismantling and Reassembly
Fewer components make dismantling, reassembly and servicing straightforward.
Lightweight and Portable
Compact construction makes handling and installation easier.
Simplified Pump Construction
Only four major components: pump housing, rear cover, rotor set and mechanical seal, allowing easy dismantling and in-place servicing.
