Key product features
- Patented non-lubricated air valve → supports stall-free operation and reduces lubrication-related maintenance
- Bolted construction → improves service access and helps control downtime risk
- Air-operated drive → suitable where electric drive is not preferred or compressed air is already available
- Seal-less diaphragm principle → avoids shaft seals, couplings and gearboxes in the fluid transfer path
- Replaceable common components → simplifies spare parts planning and maintenance work
- Material options by model → supports selection for different chemical and process media
- Compact positive-displacement design → helps installation in process equipment and confined spaces
- AxFlow selection support → helps match duty point, media and material requirements
- Service and spare parts support → helps maintenance teams plan lifecycle care
- Duty-point review before purchase → reduces risk of selecting the wrong configuration
The Yamada NDP-15 is an air-operated double diaphragm pump for industrial fluid transfer where seal-less operation, compressed-air drive and service access matter. It is relevant for process machines, chemical transfer, batch handling and maintenance teams that need a compact positive-displacement pump without shaft seals, couplings or gearboxes. Yamada NDP pumps use a patented, non-lubricated air-valve concept with independent pilot mechanisms, bolted construction and replaceable common components. Verified source material lists a 1/2" / 15 mm fluid port, maximum flow up to 51 l/min and available wetted construction options including aluminum, stainless steel 316, PVDF/Kynar, groundable acetal and polypropylene where applicable. These data points help engineers check capacity, connection size and material suitability before selection. AxFlow can help compare the duty point, media, air supply, elastomer choice and spare parts needs. The construction supports maintainability and process continuity, helping reduce unplanned downtime risk and lifecycle cost when the correct model is selected.
