Air-Operated Double-Diaphragm Pumps SeficoPower / Saibeiwo

Supply and engineering selection of SeficoPower / Saibeiwo air-operated double-diaphragm pumps for chemical processing, lithium battery slurries, surface coatings, and mining facilities across global industries.

Non-Metallic AODD Pumps B02, B05, B07, B10 Series

SeficoPower non-metallic AODD pumps of B02, B05, B07, and B10 series feature corrosion-resistant PP and PVDF bodies. Port sizes from 1/4 to 1 inch transfer aggressive chemical reagents, acids, and alkalis with dependable performance.

  • Port sizes from 1/4 inch to 1 inch with BSP and NPT threading
  • Wetted fluid casings in pure polypropylene and conductive PVDF
  • Diaphragm options in virgin PTFE, Santoprene, and NBR rubber
  • External stall-free air distribution valve without lubrication

Metallic Diaphragm Pumps B05, B1F, B15, B20, B30 Series

SeficoPower metallic AODD pumps of B05, B1F, B15, B20, and B30 series are built from aluminum alloy and AISI 316 stainless steel. Port sizes up to 3 inches handle viscous coatings, resins, and ceramic slips under continuous pressure.

  • Discharge ports up to 3 inches (75 mm) for bulk fluid transfer
  • Wetted bodies in cast aluminum alloy and AISI 316 stainless steel
  • Smooth handling of shear-sensitive paints, adhesives, and muds
  • Inherently explosion-proof pneumatic drive complying with ATEX

Specialty Long-Stroke B-L and Mining BQG Series Pumps

SeficoPower specialty line comprises extended-stroke pumps B1F-L, B15-L, B20-L, B30-L alongside rugged mining pumps BQG. The L-series reduces cycling frequency for battery slurries, while BQG pumps handle mine dewatering.

  • Long-stroke B-L engineering tailored for battery slurry duty
  • Explosion-proof BQG mining series rated up to BQG550 capacity
  • Lower cycle frequency reducing diaphragm stress and fatigue
  • Reinforced structural flanges and heavy-duty shaft guides

Diaphragms, Valve Balls, Seats, and Wetted End Kits

Wear parts for SeficoPower pumps include durable PTFE, Santoprene, Viton, and NBR diaphragms. Precision check valve balls and matching seats ensure tight fluid sealing, while complete wetted end kits simplify planned maintenance.

  • Virgin PTFE diaphragms supported by molded rubber backup discs
  • Check valve balls in PTFE, stainless steel, and elastomeric grades
  • Machined valve seats providing consistent hydraulic sealing
  • Complete wetted end rebuild kits matched to individual pump frame

Air Valve Assemblies, Pilot Valves, and Spool Sets

The pneumatic distribution system of SeficoPower pumps features external main Air Valve and Pilot Valve assemblies. A lubrication-free sleeve and spool set prevents stalling, while optimized exhaust paths reduce icing downtime.

  • External main air valve housing accessible for prompt servicing
  • Lubrication-free sleeve and spool set with low friction loss
  • Patented air passage layout reducing pneumatic icing risks
  • Pre-assembled pilot valve cartridges and dynamic rod seals

Technical Maintenance, Diagnostics, and Repair Services

Qualified engineering specialists provide maintenance and repair support for SeficoPower pneumatic diaphragm pumps. Field services include seat wear inspection, airline pressure checks, rebuild kit installation, and commissioning.

  • Onsite mechanical diagnostics and wetted part wear inspection
  • Complete pump overhaul including air motor and valve rebuilds
  • Commissioning support, airline calibration, and leak testing
  • Nameplate-based spare part identification and supply support

Material Selection Guidelines for Metallic and Non-Metallic SeficoPower AODD Pumps

The SeficoPower air-operated double-diaphragm pump portfolio is structured into corrosion-resistant non-metallic models B02, B05, B07, B10, B15, B20 and heavy-duty metallic pumps B05, B1F, B15, B20, B30.

Non-metallic configurations molded from virgin polypropylene and conductive PVDF deliver chemical resistance for acid etching, plating tanks, and aggressive chemical feed systems.

Metallic casings cast from high-grade aluminum alloy and AISI 316 stainless steel withstand high mechanical stress and abrasive erosion across industrial coatings, resins, and ceramic muds.

Extended-Stroke B-L Series Performance in Lithium Battery Slurry Manufacturing

To address the demanding conditions of lithium-ion battery electrode slurry transfer, SeficoPower engineered the extended-stroke B1F-L, B15-L, B20-L, and B30-L pump series. The elongated stroke length provides the required volumetric flow at a reduced cycling rate.

This lower operational frequency minimizes shear degradation of delicate active materials, protects conductive carbon suspensions, and extends the mechanical fatigue life of PTFE diaphragms.

Lubrication-Free Air Valve Architecture and Anti-Icing Pneumatic Exhaust

SeficoPower diaphragm pumps incorporate an externally serviceable air distribution mechanism featuring a precision-fit sleeve and spool cartridge. Aerodynamic air barrier isolation eliminates oil lubrication requirements, keeping cleanroom and processing environments free from oil mist.

Engineered exhaust chambers expand compressed air with minimized cooling drop, virtually eliminating freezing downtime during high-humidity continuous duty.
