MANTA DIAPHRAGM
PUMPS
Reliable. Efficient. Built to handle what others can't.
Key Features & Engineering Benefits
Industrial advantages of pneumatic double diaphragm architectures engineered for the harshest processing conditions.
ATEX Safe & Explosion Proof
No electrical components, motors, or wiring. 100% air-driven, making it ideal for flammable solvents, fuel transfers, and hazardous Zone 0/1 chemical plants.
Infinite Dry Running
Runs dry continuously without overheating or causing mechanical seal failure. Eliminates catastrophic pump failures when storage tanks run empty or suction lines clog.
Self-Priming & High Suction Lift
Instant dry suction lift up to 6 meters. Self-primes rapidly on cold startup without auxiliary priming loops, manual fluid filling, or foot valves.

Why Choose Manta Diaphragm Pumps?
Industrial advantages engineered to eliminate downtime, eliminate mechanical seals, and reduce fluid shearing.
100% Seal-less Design
No mechanical seals, packings, or rotating dynamic interfaces. Eliminates 95% of industrial fluid leaks.
ATEX Zone 0/1 Safe
Pneumatically driven with zero electrical sparking risk. Certified for flammable solvents, paints, and mines.
Run Dry Indefinitely
No thermal heat build-up when line runs dry or tank empties. Never suffers burn-out during unattended operation.
Instant Self-Priming
Draws liquid upward up to 6 meters from dry sumps and underground tanks with zero priming liquid required.
Solid & Slurry Handling
Passes large suspended particles, fibrous solids, and abrasive sand slurries up to 10mm without clogging.
Gentle Shear Handling
Zero high-shear impellers. Preserves delicate polymer chains, emulsions, food sauces, and latex inks.
Variable Flow Control
Adjust discharge rate from 0 to 100% simply by tuning the pneumatic air pressure regulator valve.
Extreme MOC Range
Available in SS316, Polypropylene, PVDF, Aluminum, Cast Iron, Virgin PTFE, and Santoprene for any chemical.
Engineered for Every Critical Industry
