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.

Air Switch Valve “S-Spool”
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.

・ 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.

■ Compact Design
More compact than the existing NDP-15 series models with the same port size. Ideal for mounting on equipment too.

■ Can Install with a High Degree of Freedom.
Can connect in four IN/OUT directions. The liquid connection direction can be changed freely by changing the plug mounting position. (The central position is standard)

*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.
