PTFE Double Diaphragm Drum Pumps

PTFE Double Diaphragm Drum Pumps

Quality, Performance, Reliability


Important features you'll find in Yamada F-Series PTFE pumps:


Truly Non-Lubricated Air Valve

The patented air valve on all Yamada F-Series pumps never requires lubrication or pre-packing. Plus, it is easily accessible without disassembling the pumps.


Wetted Parts

To ensure maximum corrosion resistance, purity levels and low particle generatation, Yamada pumps feature diaphragms, liquid chambers and manifolds that are machined from 100% virgin PTFE. 
Polypropylene and High Density Polyethylene are used in the air motor section (non-wetted) to ensure resistance in a corrosive environment.


Extended Performance Diaphragms

All Yamada F-Series diaphragms are manufactured from 100% virgin PTFE. As a result, these diaphragms will last up to twice as long as those found in many competitve pumps. In addition, incorporating minimal shaft travel reduces pump pulsation.


Clean Room Manufactured

Yamada F-Series pumps are manufactured, DI water tested, nitrogen purged, and double bagged under class 1000 clean room conditions according to stringent quality control standards and procedures.


Most Complete Line Available

Yamada offers five sizes of F-Series pumps for your applications with adjustable flow rates up to a maximum of 35 gallons per minute.


Yamada is proud to offer the largest line of field-proven, high purity air-operated double diaphragm pumps.


End-User Maintenance

Yamada F-Series pumps are easily end-user maintainable and are backed with readily availalbe service and parts worldwide.


Explosion-Proof Operation

Air operation eliminates a potential source of ignition, so thee's no need to take additional preventative measures when pumping volatile or flammable liquids, or when using the pump in potentially hazardous environments.



Yamada warrants all pumps for one year from date of installation.

The Yamada Advantage

Yamada Air Powered Double Diaphragm Pumps: Engineered for High Performance. Manufactured for Long Life.

Rugged, Bolted Construction

All Yamada pumps feature bolted construction, which eliminates leaks and simplifies post-maintenance reassembly. Bolted construction is superior to clamp band retainers, which frequently require frustrating, unnecessary leakage rebuilds from misalignment during reassembly.

Patented Air Valve Technology

Incorporated in every Yamada Air Powered Double Diaphragm pump

Yamada air valve technology is the heart of the air-powered double diaphragm pump and determines reliability. Yamada holds three patents on its field proven valve and enjoys a superior reputation throughout the industry.
