G15 series
Simple Structure for Easy Maintenance!
A diaphragm pump that can transport a wide range of liquids, from highly corrosive to highly viscous liquids.
While it has a maximum discharge of 60 L/min and is compact, the new design diaphragm provides for an approximate 20% increase in the maximum flow rate from a diaphragm pump of the same port size.
Can pump out more efficiently from the tank by self-suction, with no pump-priming required. The safety structure does not require explosion-proof measures, so it can be used anywhere. By simply opening and closing the valve, cutting off the flow at the end point is possible or water discharge can be controlled easily and safety.
The G15 series has a nominal diameter of 1/2" (15 mm) and a maximum flow rate of approximately 62 L/min.
The maximum size solid is 1 mm or less.
■ Main Applications
Alcohol/Transfer of Ethanol/Transfer of Lubricant and Hydraulic Oil/Supply of Paint to Roll Coater/
Collection of Cutting Oil/Transfer of Pure Water and Chemicals/Application of Adhesives/Spray Glazing/Mounting on Equipment/
Transfer of Inks and Pigments, Etc.
Features
■ Compact yet High Flow
Rate Employs new-design diaphragm. 
■ Stable Operation
Employs new-design switch mechanism S-Spool.
The high-performance and high-reliability new air switch valve mechanism minimizes the risk of the pump stalling.
◆ Air Switch Valve “S-Spool”
| ・ S-Spool (Step spool) + New Center Rod Prevents Stoppages during Operation The risk of stoppages during operation is minimized even during low-stroke. |
・Design without Pilot Valve Fewer parts = fewer failures. |
・Completely Oil-free Does not require regular lubrication. |

*1 The maximum supply air pressure for a type with a resin-made pump body will depend on the liquid temperature.
*2 The water discharge is provided as a rough approximation only. The discharge will differ depending on factors such as the liquid to be transferred and the piping conditions.
*3 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.

◆ Air Unit
2piece set (Air Filter + Regulator)
Removes moisture and debris from the supply air and protects the pump mechanism.
An air filter and regulator are included in one set depending on the usage conditions.
Yamada diaphragm pumps can be operated without lubrication with two sets of air except under the following conditions.
● DP-10 series, NDP-H series
● For continuous operation of minimum 1 hour
● For use with fluids and environments of minimum 70°C
● 2-piece set has a 1/4" inner diameter.
*Prepare the connection materials separately according to the usage conditions.
*Use the dedicated bracket and air hose when attaching to the pump.
