Yamada Air Operated Double Diaphragm Pumps
Can we help?
These pumps are lightweight, compact and easy to use for pumping a wide range of liquids. As they are air operated they are ideal for pumping volatile or inflammable liquids in hazardous areas.
Self-priming from a dry start these pumps are ideal in situations where liquid has to be pulled from a container. The pumps can also run dry.
The robust construction reduces maintenance to a minimum.

Recommended Products
Brearley Mineral Insulated Thermocouples
Brearley Mineral Insulated Thermocouples are metal sheathed cables with thermocouple conductors which are insulated from each other and the sheath by highly compacted magnesium oxide.
Conductors are safe from environmental contamination, ductile and highly responsive.
The cables are water, oil and gas resistant, extremely robust and are eminently suitable for applications where high or low temperature, corrosion, vibration, pressure and other extreme conditions exist.
Brealey Mineral Insulated Thermocouples can be designed and tested to comply with the requirements of AMS 2750D and NADCAP.
Plastic Paddle Flow Switches
TRIMMABLE PLASTIC PADDLE FLOW SWITCHES
The V8 paddle flow switch is ideal for protection of unattended equipment from damage or loss of production.
Operation is simple and dependable. In most applications, the switch is normally off while there is sufficient flow of liquid or air. When flow stops, the vane spring moves the vane, actuating a single pole double throw switch rated at 5A 120/250Vac to start or stop a motor,pump, engine, etc; operate a damper or valve; shut down a burner or actuate an alarm or signal.
The V8 Flow Switch has a leak proof body and vane constructed of tough durable Polyhenylene Sulfide (equivalent to RYTON®) which has excellent chemical resistance. The full size trimmable vane is provided with moulded-in graduations allowing for installation in pipes from 1 inch to 6 inch diameter. The V8 control is UL recognized as an industrial motor controller per UL standard 508, suitable for mounting in a protected environment.
Platon Averaging Pitot Tube: Flo-Bar
The Flo-Bar is an Averaging Pitot Tube flow sensor for use on pipes/ducts or chimneys. Differential pressure created across the Flo-Bar has the standard square root relationship to flow rate, making a simple, removable sensor for installation or retrofit on flowlines of any size.
The unique design of the Flo-Bar profile provides a high accuracy, wide rangeability sensor: the standard integral manifold allows simple process isolation and easy installation of a DP measurement cell.
