YTS has been producing a large range of Air Operated Double Diaphragm Pumps in Japan since 1978 and now offers a huge line-up of standard & customized pumps available in many different sizes and materials. 

All YTS pumps are specifically designed to be used in process type liquid transfer applications and offer various engineered design features enabling efficient high performance liquid transfer and high operational reliability. They can be easily and quickly serviced and maintained even without pulling the pump from the process line. All serviceable wear components are modular and fully replaceable offering simple low cost replacement over a long lifetume of use. 

Due to their engineered desing, and due to the specific utilizations of moderns high tech materials, all YTS pumps can be operated without the need for Air Line Oil or Grease Lubricants. They therefore offer safe, clean zero emissions pump operation, protectiong people, processes and work environments from dangerous airborne vaporized contaminants. 

The new generation Looped C Spool and the thrid generation Coil-Spring Air Valve offer much improved pumping performance, air consumption, operational reliability and reduced maintenance. Pumps fitted with the new patent pending Air EcoRing offer on average, 16% better air consumption figures witout any negative effects to overall pumping performance. 

All pumps incorporate independent high performance Pilot Valves for unrivalled reliability and high speed short stroke operation. YTS pumps utilize large diameter air porting and will resist stalling and resist freezing in nearly all conditions. They have leak resistant design features such as; fully bolted construction, machined liquid mating surfaces and registeredfit body asembly. All YTS pumps are torqued and rogorously tested prior to shipment. 

CAPABILITIES:
DRY RUN
Diaphragm Pumps can Run Dry for extended periods with no damage to the pumps moving pumps. Also when running dry the pump will not overheat.

TRANSFER SOLIDS
Due to their unique design, liquid slurries as well as large sized solids such as beads, stones, etc. can be pump with ease.

VARIABLE FLOW RATES AND DISCHARGE PRESSURE
By adjusting either the air regulator or a liquid discharge valve, it's possible to operate the pump anywhere between 0.1 liters per minute to full capacity. Liquid discharge pressure can be adjusted from less than 1bar up to 8.4 bar, on some larger pumps.

DEAD HEAD
A Diaphragm Pump can run against a semi closed or fully closed liquid discharge valve "Deade Head" without damage or wear to the pump. Therefore the Discharge Line may be close fully at any time and even closed repeatedly. There will be no Power consumed, no Temperature increase and no damage to the pump, it will simply stop.

SELF-PRIMING
Diaphragm Pumps can operate dry and they can also generate relatively high vacuum pressure, thus allowing the pump to self-prime.

SAFELY TRANSFER FLAMMABLE AND HAZARDOUS MATERIALS
Diaphragm Pumps are powered by compressed air and do no have any kind of electrical connections. They cannot overheat and the cooled naturally during operation by the supply of compressed air. When correctly earthed, they are considered safe to use when pumping flammable liquids or when used in Explosive Environments.

MADE IN JAPAN
All YTS pumps are designed engineered and manufactured in Japan. Every pump is torqued ans tested prior to dispatch to ensure correct performance and optimal leak proof operation.
