Mebo / Meibao Pump Chemical Metering and Centrifugal Pumps

Mebo / Meibao Pump chemical metering feeders, centrifugal transfer pumps, and sealless magnetic drive units: engineered fluid handling solutions and replacement components.

Mechanical diaphragm dosing pumps Mebo MBT

Mechanical diaphragm metering pumps Mebo (Meibao) MBT series are engineered for continuous chemical injection. Pump heads manufactured from pure PVC and virgin PTFE provide chemical resistance when handling acidic solutions, alkaline media, and coagulants.

  • Calibrated chemical flow capacity range spanning from 66 to 270 liters per hour
  • Discharge operational pressure ratings up to 8 bar with steady dosing volume
  • Micrometer adjustment dial regulating stroke displacement linearly from 0 to 100%
  • Standardized DN15 and DN25 flange connections for leak-tight plumbing integration

Heavy-duty chemical dosing pumps Mebo MBK

Heavy-duty industrial metering pumps Mebo (Meibao) MBK series are designed for chemical processes operating under elevated discharge backpressures. A rigid iron gear housing and a 0.4 kW three-phase electric motor ensure continuous operation under severe duty.

  • Elevated delivery pressure ratings reaching 10 bar against line resistance
  • Chemical metering capacity adjustable within 90 to 306 liters per hour
  • Heavy-duty worm gear transmission running in continuous oil lubrication
  • Multi-layer PTFE diaphragms compatible with aggressive oxidizing solutions

Centrifugal chemical transfer pumps Mebo MP

Horizontal centrifugal chemical pumps Mebo (Meibao) MP series are engineered for transferring corrosive acids, alkalis, and process solutions. The jointless molded impeller and polymer volute eliminate leakage while handling liquid media at temperatures up to 90°C.

  • High volume fluid transfer delivery reaching up to 50 cubic meters per hour
  • Elevated hydraulic delivery head reaching up to 32 meters vertical lift
  • Volute bodies molded from reinforced polypropylene FRPP and virgin PVDF
  • Liquid-cooled mechanical seal providing protection during brief dry running

Sealless magnetic drive chemical pumps Meibao

Sealless magnetic drive pumps Meibao (Mebo) eliminate leakage risks when moving toxic and volatile chemical reagents in electroplating and surface finishing. Drive torque transmits across a hermetic containment shell without requiring traditional dynamic shaft seals.

  • Completely sealed fluid chamber eliminating dynamic rotary shaft seals
  • Internal bearings fabricated from high-purity alumina ceramic and silicon carbide
  • Wetted components engineered from carbon-filled fluoropolymer compounds
  • Reliable handling of concentrated acids, alkaline baths, and volatile solvents

Self-priming chemical pumps Meibao with idling protection

Self-priming chemical pumps Meibao (Mebo) incorporate an integrated gas separation chamber that facilitates fast fluid suction from underground sumps and storage vessels. The internal seal design prevents thermal overheating during initial non-primed startup sequences.

  • Dependable suction lift capability reaching 5 to 6 meters from deep sumps
  • Built-in internal check valve retaining liquid prime inside the pump chamber
  • Protective seal architecture safeguarding internal components during idling
  • Continuous drainage of waste liquids from underground tanks and rinse baths

Diaphragms and repair kits for Mebo / Meibao pumps

For scheduled maintenance and overhaul of Mebo / Meibao Pump equipment, we provide replacement components and service kits. Timely replacement of flexible diaphragms and check valve seats restores calibrated metering accuracy and avoids costly manufacturing line interruptions.

  • Multi-layer working diaphragms fabricated from pure virgin PTFE polymer
  • Precision check valve seats and balls engineered from inert fluoroplastics
  • Chemical O-rings molded from resilient fluoroelastomer FKM and EPDM rubber
  • Replacement wetted liquid ends, drive pushrods, and worm gear repair kits

Engineering selection of Mebo (Meibao) MBT and MBK chemical metering pumps

Proper volumetric sizing and system pressure calculations are essential when engineering chemical dosing skids using Mebo / Meibao Pump units. The MBT series diaphragm metering pumps handle atmospheric tanks and pressurized injection manifolds up to 8 bar with flow rates reaching 270 L/h.

For heavy chemical processing networks requiring delivery pressures up to 10 bar, the MBK series provides a rugged 0.4 kW drive mechanism. Linear micrometer stroke adjustment allows accurate volume tuning from 0 to 100%, delivering consistent fluid repetition with variations under one percent.

Fluid end polymer options for corrosive acid and alkali handling

Chemical compatibility of wetted liquid ends on Mebo / Meibao Pump units dictates extended service life in aggressive reagent environments. Pure PVC pump heads suit neutral fluids, brine solutions, and coagulant mixtures.

For concentrated sulfuric acid, hydrochloric solutions, nitric blends, and strong oxidizers, pump heads molded from virgin PTFE or PVDF are deployed.

A multi-layer diaphragm with a solid PTFE face isolates internal drive gearing from process liquids, preventing seal breakdown and ensuring hermetic operation during continuous 24/7 industrial duty cycles.

Centrifugal chemical transfer pumps Mebo MP with dry-run protection

In chemical manufacturing plants and PCB etching facilities, system upsets often cause suction line dry-out. Horizontal centrifugal pumps Mebo / Meibao MP series incorporate an internal liquid-cooled mechanical seal.

The circulating fluid path removes friction heat from alumina ceramic rings using retained chamber volume, preventing thermal shock when fluid supply is briefly interrupted.

Volute bodies molded from reinforced polypropylene FRPP or fluoropolymer PVDF withstand hydraulic pressure surges and corrosive fumes at temperatures reaching 90°C.

Sealless magnetic drive Meibao pumps for electroplating lines

Surface finishing and electroplating installations require fluid handling systems that eliminate external chemical leaks. Sealless pumps from Meibao with magnetic drive couplings utilize a solid polymer rear containment shell.

Motor drive torque transmits across the non-metallic barrier through high-coercivity permanent magnets.

Eliminating dynamic mechanical shaft seals prevents hazardous vapor emissions into the workplace, protects plant personnel, and extends maintenance intervals during continuous filtration of metal plating baths.

Maintenance procedures for metering diaphragms and check valves

Consistent chemical dosing accuracy in Mebo / Meibao Pump units depends directly on the integrity of internal check valve balls and the elastomeric diaphragm.

During routine servicing every 3,000 operating hours, valve seats and precision balls molded from fluoropolymer or alumina ceramic undergo close inspection. Particulate accumulation or salt scale build-up causes discharge pressure decay and loss of linear stroke accuracy.

When installing replacement diaphragms, cross-tightening head bolts ensures uniform clamping without localized stress.

Suction line installation guidelines and cavitation prevention

To maintain full hydraulic performance in Mebo / Meibao Pump installations, suction piping must minimize fluid friction. Suction pipe diameters should match or exceed the pump inlet diameter, maintaining an upward slope toward the pump to prevent vapor pockets.

For self-priming configurations, flange joint seals and foot valve sealing require verification. On positive-displacement metering lines, pulsation dampeners and backpressure valves should be installed to smooth hydraulic surges and preserve downstream flow meter sensors.
