• SAMOA Directflo AODD Pumps Catalogue  

Diaphragm Pumps are considered to be the most versatile pumps ever built. Its' quick, easy, plug-and-play design, portability, fixed fluid volume displacement, easy flow and discharge pressure variability makes it an ideal pump to handle many fluid transfer applications.

SAMOA - A world leader in pneumatic positive displacement pumps, have been in the forefront of introducing energy-efficient pump technologies since 1958.

SAMOA manufactures air operated diaphragm pumps with the globally patented frictionless pivoting air motor, which ensures the fastest reciprocation action in the industry, resulting in a low energy, low pulsation, low noise, low turbulence, low vibration pump. The pump can be operated at higher pressures without any icing and can be operated at extreme low pressures without any stalling.

Features & Benefits:

Air Valve:

• Frictionless, pivoting, virtually non-wearing valve.
• The patented air valve features the fastest reciprocation action in the industry, making the pump incredibly efficient and ensures low noise, low vibration, low pulsation operation.
• The air valve doesn't require any lubrication and can work with dry, damp and even contaminated air without any trouble.
• The patented 3S technology ensures pump won't freeze leading to icing even at high operating pressures and won't stall even at extreme low pressures.
• Externally repairable and replaceable cartridge design air valve makes maintenance easier like never before. The repair time reduced from 50 minutes to less than 5 minutes.

Pump Design

• Solid, robust construction with higher material thickness to withstand toughest applications.
• Optimized fluid paths to reduce drag and minimise wear caused by abrasion.
• Availability of both single-piece, overmoulded, convoluted diaphragms as well as conventional design diaphragms.
• Fluid ports available as BSP/NPT threaded or ANSI/DIN Flanged.
• Bolted construction for leak-free operation with same size bolts used for easier maintenance.
• Very limited moving parts and availability of modular kits for easy maintenance.
• Matches relative mounting dimensions of main competitor brands making switching easier, without the need of expensive re-piping.
• All Aluminium pumps are electrophoretic epoxy coated for enhanced corrosion protection.
• CE ATEX, UKCA, EAC compliant (all metallic models and all conductive non-metallic models).
