SANDPIPER Heavy Duty Ball Valve Industrial Pumps
SANDPIPER Heavy Duty Ball (HDB) pumps handle highly viscous liquids and abrasive industrial slurries. Weighted check balls and optimized flow paths prevent internal solids settling. Available in HDB1-1/2, HDB2, HDB3, and HDB4 models with replaceable wear-resistant valve seats.
- Heavy duty models HDB1-1/2, HDB2, HDB3, and HDB4 for thick media
- Transfer of thick sludges, slurries, and solids-laden industrial mixtures
- Bottom discharge porting with weighted balls preventing solid settling
- Wet end replacement kits, PTFE diaphragms, and valve seat inserts
SANDPIPER Heavy Duty Flap Valve Slurry Pumps
SANDPIPER Heavy Duty Flap (HDF) pumps are built for abrasive slurries with large suspended solids. Hinged flap valves pass large non-settling solids up to 75 mm without clogging. HDF1, HDF2, HDF3, and HDF4 feature top suction ports and durable modular flap seals.
- HDF series models HDF1, HDF2, HDF3, and HDF4 for demanding slurries
- Clear passage for large solid particles and debris up to 75 mm size
- Top suction inlet design enabling smooth gravity-assisted slurry intake
- Replaceable flap valve blades, elastomeric hinges, and diaphragms
SANDPIPER Containment Duty Dual Diaphragm Pumps
Containment Duty pumps protect personnel and facilities when moving hazardous and toxic media. Dual diaphragm construction with intermediate barrier chambers prevents external fluid leakage. Units feature visual sight glasses and electronic leak detection probes.
- Dual diaphragm fluid containment engineered for toxic and reactive media
- Pumping hazardous chemicals, volatile solvents, and corrosive acids
- Intermediate barrier chamber with visual and electronic leak detection
- Primary and backup diaphragm sets, visual gauges, and sensor probes
Cognito Electrically Operated Double Diaphragm Pumps
Cognito EODD pumps combine positive displacement performance with energy-efficient electric drives. Operating without plant compressed air, they include smart IoT monitoring and leak detection. Seal-less construction significantly reduces regular maintenance downtime.
- Energy-efficient electric mechanical drive running without compressed air
- Low energy consumption fluid transfer for factory automation systems
- Integrated IoT operating telemetry with automatic leak detection
- Diaphragm replacements, drive bearing assemblies, and sensor kits
