SANDPIPER Model Pumps

SANDPIPER Evolution Series

Evolution means optimized performance without sacrificing proven reliability. These pumps have undergone an engineering EVOLUTION, leveraging trusted and proven product designs to improve their performance by application of advanced engineering methods. Unlike the competition, these pumps are fully interchangeable with prior models.

WHEREVER YOU SEE THIS BADGE: These pumps have gone through our Evolution performance improvement. Watch for more Engineering Evolutions to come in the near future!

SANDPIPER’s unique combination of best-in-class max flow rates and lowest air consumption makes them the most efficient and economical pumps available.

Max flow rate: The S20 is the world leader in maximum flow rate, with up to 32% higher capacity, allowing you to get your work done faster.
Air consumption: The S30 requires up to 56% less air to operate, reducing the load on your compressed air system and lowering operating costs.
Air economy: SANDPIPER’s metallic standard-duty pumps provide up to 2.5 times more gallons out for every cubic foot of air supplied.
Annual savings: SANDPIPER’S metallic standard-duty pumps can save you up to $3,543 in annual operating costs.

Evolution Features

Serviceability: The Air Distribution System (ADS) is one of the most frequently serviced parts of any AODD pump. Only SANDPIPER’s ESADS+ feature allows access to the complete ADS without removing the pump from service. Repair or clean in 5 minutes vs. 55 minutes for competitors.
Trusted in Simplicity: SANDPIPER’S original Air Distribution System (ADS) has been proven to stand the test of time. Our ADS is fully interchangeable, repairable and inline serviceable. Other manufacturers have frequently changed ADS designs creating issues with interchangeability, obsolete inventory and increased cost of ownership.

SANDPIPER Signature Series

Even in the most severe applications and environments, the SANDPIPER Signature Series™ of AODD pumps are engineered to provide industry-leading durability and performance. The SANDPIPER signature series pumps include heavy-duty flap, heavy-duty ball, and containment duty pumps.

Heavy-Duty Flap Valve: For fluids containing up to line size solids.
Heavy-Duty Ball Valve: For fluids containing settling, suspended & floating solids.
Containment-Duty Ball Valve: Exclusive AODD pumps featuring superior fluid containment; protecting your people, environment and pump.

Containment Duty Ball Valve Pumps

The only complete line of AODD pumps featuring superior fluid containment; protecting your people, environment & pump. In typical diaphragm pump applications, when the pumping diaphragm is breached, the fluid enters the air distribution system and escapes into the environment through the muffler, requiring immediate service. With containment duty pumps, when the pumping diaphragm is breached, the fluid enters the containment chamber and visual indicator sight tubes, alerting the user. The fluid is fully contained so the pump can continue running until the operation is complete or maintenance can be scheduled.

NO LOST SYSTEM FLUID

Perfect for pumping fluids that are dangerous to your people or the environment. Makes repairs easy, as the Air Side of the pump does not get contaminated.

NO COSTLY CLEANUP

When a typical AODD pump has a diaphragm breach, the system fluid passes through the Air Side of the pump and out into the environment. Clean-up is expensive and time-consuming.

2 DIAPHRAGMS ARE BETTER THAN 1

Features two diaphragms. The space between the diaphragms creates a barrier between the Air Side and Wet Side of the pump, preventing escape of the fluid to the environment when the pumping diaphragm becomes breached.

VISUAL LEAK DETECTION

Alerts the user when there is a diaphragm breach before any of the system fluid can escape to the environment. Also available with electronic and mechanical leak detectors.

SANDPIPER G-Series | GAS OPERATED DOUBLE DIAPHRAGM (GODD)

Traditional AODD pumps are designed for use with air only. Over the years, oil and gas operators have opted to power their diaphragm pumps with easily accessible natural gas. The application of AODD pumps driven by natural gas created a unique set of safety requirements that previously did not exist.

In 2003, SANDPIPER recognized the need and partnered with the Canadian Standards Association (CSA®) to lead the development of the first-ever safety certification for Gas Operated Double Diaphragm (GODD) pumps. CSA Certified GODD pumps are designed and tested to be powered by natural gas when installed according to the certification and local requirements. SANDPIPER is the only GODD pump manufacturer that offers a full range of CSA Blue Star (ANSI LC6) / Blue Flame (Canadian Technical Letter R-14) Certified pumps from ½” to 3″ sizes.

Our G-Series Dual Power pump line carries the most stringent certifications for safety and reliability for oil and gas applications and has been used extensively across midstream and upstream applications.
