MetiRota benefits from innovative rotor design and continuous accumulation ofcustomer application experience. The latest profile design achieveslow-pulsation, high-efficiency conveying, improving the sealing state betweenthe rotor and the pump housing from point sealing to line sealing. Thisprevents backflow caused by wear, maintains stable and efficient conveying,further extends rotor life, and reduces maintenance costs.
● Gas-liquid mixed conveying ● Strongself-priming ● Wear-resistant ● Easy maintenance ● High viscosity ● High flowrate
Reversible Flow:Fully symmetrical design allows complete flow reversibility (forward andreverse rotation) simply by changing the drive direction.
l Loading/UnloadingVehicles: One pump can handle both loading and unloading tasks.
l MembraneTreatment: Forward rotation for suction, reverse rotation for flushing.
l OilTank Cleaning Operations: Forward rotation for collecting sludge at the tankbottom, reverse rotation for high-pressure tank cleaning.
l WasteOil and Sewage: Forward rotation for normal operation, reverse rotation forclearing blockages.
l EasyInstallation: No need to distinguish direction during on-site installation;only motor wiring adjustments are required.
Gas-Liquid-Solid Mixed Conveying:Suitable for mixed conveying of gas, liquid, and solids, such as unloading andclearing residues for gasoline, diesel, and methanol, offering significantadvantages over other pump types.
l OilDepot Clearing: Top clearing with minimal residual oil.
l Methanol,Naphtha, etc., Unloading: Fast unloading, resistant to flow interruption, highefficiency.
l CrudeOil Conveying: Suitable for conveying crude oil with high gas content in oilfields.
Strong Self-Priming:Vertical self-priming capability reaches up to 9 meters; no need for priming orfilling the pump—direct start-up achieves self-priming.
l Sewage,Rainwater, and Waste Oil Lifting: Dry installation above ground, convenient formaintenance, inspection, and high operational safety.
l Clearingand Unloading: Capable of long-distance and deep self-priming.
l VacuumSewage: Suitable as the main pump for vacuum toilets, vacuum drainage systems,and high-speed train sewage suction units.
l Self-primingcapability up to 9 meters, making it the pump type with the strongestself-priming ability.
Wear-Resistant:The wear-resistant pump housing is integrally cast. When conveying highlyabrasive media, radial protective liners can be simultaneously selected. Thestandardized, wide inlet ensures smooth passage for viscous (up to 100,000 Cp)or solid-containing media (up to 70 mm).
l Sludgeand Sewage Conveying:
l CoalWater Slurry Conveying:
l OilSludge and Scum Conveying:
l ActivatedCarbon Conveying:
l DrySludge Conveying:
Pumpspeed typically ranges between 100-600 rpm. The low-speed operation reduceswear rate. The pump housing includes built-in protective liners andwear-resistant steel at the inlet, offering high wear resistance and easyreplacement. The rotor is coated with reinforced NBR (or HNBR) rubber.
High Viscosity:Capable of conveying media with viscosities up to 100,000 Cp while maintaininghigh efficiency in high-viscosity conveying applications.
l CrudeOil and Heavy Oil Conveying: Suitable for conveying high-viscosity crude oil,residual oil, and asphalt. The insulated jacket design prevents low-temperaturesolidification and blockages, maintaining fluidity.
l Polymerand Resin Media: Efficiently conveys viscous chemical materials such aspolyether polyols, synthetic resins, and adhesives. The three-lobe circular arcrotor design reduces shear force, protecting material properties.
l LubricatingOil and Process Oil Handling: Handles high-viscosity lubricating oils, baseoils, and additives. Low speeds (not exceeding 500 rpm) help reduce energyconsumption.
Easy Maintenance:The quick-open pump cover and unilateral bearing support design for the rotorenable online maintenance (i.e., parts replacement and repairs can be performedwithout disassembling the pump or pipelines).
High Flow Rate:The flow rate range for rotary lobe pumps is 0.5-2,000 m³/h. Low Shear, LowPulsation: The short travel distance of the medium inside the pump body resultsin low shear and pulsation, ensuring smooth and stable conveying.
