Drum Pump (Special specifications)
![](https://ap.yamadacorp.co.jp/products/images/dram-thumb-450x450-3380.jpg)
Convenient for Small Portioning Work from Drum Containers!
Safe Design with Intrinsically Explosion-Proof Specification.
A drum type diaphragm pump that is fitted in a drum container, allowing for the safe transfer of fuel and other solvents. The pump can be used with ease by simply inserting a suction pipe into the 2B bung of the drum container, and securing it with the included bung adaptor.
The DP-10B〇□-D series has a nominal diameter of 3/8" (10 mm), a maximum flow rate of approximately 18 L/min and a maximum size solid of 1 mm or less.
The NDP-20B〇□-D series has a nominal diameter of 3/4" (20 mm), a maximum flow rate of approximately 90 L/min and a maximum size solid of 2 mm or less.
Purchase the hose and discharge valve separately in accordance with the usage application.
Only aluminum (ADC12/AC2A/SGP) is available as the body material for the NDP-20 series, due to the net weight and operation aspects.
The suction tube method is recommended for the SUS material model.
■ Main Applications
Transfer of Fuel and Other Solvents from Drum Containers
Features
■ Convenient for Small Portioning Work from Drum Containers
Designed in a form that is easy to use for drum containers, based on the DP-10/NDP-20 series diaphragm pump.
The pump can be used with ease by simply inserting a suction pipe into the 2B bung of the drum container, and securing it with the included bung adaptor.
■ Yamada’s Proprietary Design Air Switch Valve “C-Spool "
The air switch valve in the center section of the diaphragm pump is completely oil-free, so it does not require regular lubrication.
The operation assist using a C-spring suppresses stoppages during operation, and achieves stable operation.
◆ Air Switch Valve “C-Spool”
· The C-spring Prevents Stoppages during Operation Achieves stable operation. |
· Equipped with a Reset Button Downtime due to pump stoppages in the case of abrasion of the air switch valve is kept to a minimum. |

· Completely Oil-free Both the air switch valve and the pilot valve that activates the air switch valve at the stroke limit are designed to be oil-free. Does not require regular lubrication. |
· Simple Replacement No need to disassemble the pump when replacing it. |

*1 The water discharge is provided as a rough approximation only. It will differ depending on the usage conditions, etc.
*2 Maximum flow rate is a value indicating the pump capacity. We recommend selecting a size that allows some leeway, taking into account the impact on the life span of the diaphragm.
*3 The hose and gun are not included. Please purchase separately.
*4 The standard material of the bung adaptor for the DP-10-D series is “ADC12/A5056” aluminum. We build to order it with SUS304 for handling chemicals, by special order.
