WARREN RUPP is a world leader in the design and manufacture of pneumatic double diaphragm pumps, the production of the famous brand SandPIPER (SandPIPER) pneumatic double diaphragm pumps. SandPIPER pumps are widely praised for their simple design, numerous features, advanced technical features, and excellent performance in a variety of industrial applications. The newly designed SandPIPER ⅱ metal pump provides aluminum alloy, cast iron, stainless steel and Hastelloy pump body materials. Widely used, can meet all kinds of industrial liquid transport requirements. In conveying no particles, low to high viscosity medium can provide special suction lift.

Product features: safety explosion-proof gas source for power, will not produce sparks, thoroughly explosion-proof. The SandPIPER pump can be used in explosion-proof environment.

Good anticorrosion performance of the pump body material selection, according to the corrosion characteristics of the medium to choose the best material. Can be used in a variety of corrosive media.

No sealed design, no motor -- no leakage

Due to pneumatic and no seal design. No motor, no leakage, no environmental pollution.

Conveying wear media and shear media

Because of the low inner body flow rate, can transport high wear medium and shear medium, will not cause damage to the pump and medium.

Conveying viscous medium

Can transport medium with high viscosity or containing particles. Almost every medium from water to ketchup.

Completely imbibition

SandPIPER ⅱ pump does not need irrigation pump under conventional conditions, completely self-priming.

Traffic is adjustable

Only need to control the air source, can make the pump flow from zero to the maximum arbitrary change.

Not afraid of idling, not afraid of holding pressure

Compared with conventional pumps, SandPIPER pumps do not damage the pump body under any idling condition.

Multiple outlet connection modes

Can provide a variety of outlet, including: upper outlet, lower outlet, side and double outlet, etc.

Upper outlet - General purpose (not suitable for media with precipitating particles).

Lower outlet - for media with precipitating particles.

Side and double exits - special purpose.

Bypass and return valves are not required

When the outlet pressure equalizes with the driving pressure, the pump automatically stops, SO SIMPLY CLOSING the outlet and the pump STOPS, eliminating the need to INSTALL an EXPENSIVE bypass system.

No dead point guarantee

After years of practice and improvement, WARREN RUPP guarantees that all SandPIPER pneumatic double diaphragm pumps will not start poorly.

ESADS PLUS (external maintenance air valve system);

WARREN RUPP's patented design eliminates the need for lubrication, and repairs are performed from outside the pump body, resulting in significant savings in repair time and downtime, saving customers money and increasing productivity.
