Yamada Air-Operated Double Diaphragm Pumps
Keep Difficult Fluids Moving
Corrosive chemicals, abrasive slurries and thick liquids can cause recurring pump maintenance and interrupt production. SCG Process helps you select a Yamada air-operated double diaphragm (AODD) pump matched to your fluid, transfer requirements and installation.
From emptying drums and totes to moving wastewater sludge, we assess material compatibility, suction conditions and available compressed air to help you choose a suitable configuration.
Where Can a Yamada AODD Pump Fit?
Chemical Transfer
Transfer acids, caustics and other process chemicals between tanks or process stages. SCG helps match wetted materials to the chemical, concentration and temperature, alongside your flow and pressure requirements.
Drum and Tote Emptying
Move compatible oils, chemicals and other liquids from drums and totes into your process. SCG assesses viscosity, suction piping and discharge requirements to select a configuration suited to container emptying and intermittent operation.
Wastewater and Sludge Transfer
Move process wastewater, collected waste and sludge containing suspended solids. SCG evaluates particle size, solids concentration and abrasiveness to match the pump to the transfer duty, including suitable filter-press feed applications.
Mining and Industrial Slurries
Transfer abrasive slurries and aggressive process fluids between collection points, tanks and process stages. SCG assesses solids loading, particle size and fluid chemistry to select materials and configurations suited to the duty.
What Is Making Your Fluid Difficult to Pump?
Frequent seal maintenance
AODD pumps have no rotating shaft seal, eliminating that maintenance point. Diaphragms and check valves still require inspection and replacement.
Corrosive or abrasive fluids
A choice of wetted materials helps address chemical compatibility and abrasive wear. SCG helps select the combination suited to your fluid and operating conditions.
Thick liquids or suspended solids
Suitable AODD configurations can transfer viscous liquids and solids-bearing fluids. Pump size, valve design and operating speed must account for viscosity, particle size and solids concentration.
Changing levels and intermittent transfer
Self-priming capability can suit container emptying and suction-lift installations. Actual performance depends on the fluid, lift height and suction piping.
Why Yamada for Demanding Transfer Applications?
Yamada’s AODD range combines compressed-air operation with material and configuration choices for challenging fluids.
No external air-valve lubrication
Yamada’s NDP Series uses a non-lubricated air valve, removing the need for external lubrication of that valve.
Air-valve design that resists stalling
A spring-assisted shifting mechanism helps prevent the air valve from stopping in a neutral position, supporting reliable cycling and restarting.
Serviceable air-valve components
Individual air-valve components can be replaced without replacing the complete valve and housing, giving maintenance teams a more targeted repair option.
SCG helps match these features to your operating requirements, alongside pump sizing, material compatibility and installation conditions.
