SANDPIPER CONTAINMENT-DUTY 1″ (25 mm) PUMP: PROTECTING PEOPLE, EQUIPMENT AND THE ENVIRONMENT

For more than 55 years, manufacturers across multiple industries that involve hazardous materials have trusted SANDPIPER to protect people, equipment, the environment and the material being pumped.

The SANDPIPER ST1 AODD pump provides unsurpassed fluid containment in the event a diaphragm is breached. This leak-free pump is designed to be driven by compressed air or nitrogen.

Why Use Containment-Duty Pumps?

Environmental concerns: When fluids (like those listed below) escape to the environment, significant time and effort is required on clean up and material recovery. Additionally, the costs of downtime, lost production, manpower, equipment replacement, disposal fees and fines can be excessive. Preventing leaks when handling these substances provides a more efficient operation and avoids the damaging effects of environmental and human exposure to these toxic fluids.

Paints, inks and coatings
Adhesives and resins
Chemicals and petrochemicals
Oils and hydrocarbons
Acids, caustics and corrosives
Plastics and polymers
Contaminated water and wastewater
Pesticides and herbicides
Fertilizers
Preservatives
Mercury
Phthalates

High cost of lost fluid: When fluids (like those listed below) escape to the environment, the cost of losing them is significant. Lost fluid means lost profit.

Drugs and pharmaceuticals
Foods
Cyanotic-based paints
Precious metal-based fluids
Cosmetics
Perfumes
Printer inks
Beer and alcohol
Blood
Creams and lotions

Fluids that need to be contained: Even non-toxic fluids, like clean water, can create hazards, annoyances and safety concerns if people are in or around the area surrounding a pump when a diaphragm fails. When dealing with toxic and hazardous fluids, the need to contain leaks goes from a nuisance to a critical safety need.

ST1 Containment-Duty Pump Features

Leak detection: All containment-duty pumps are designed to accommodate visual, mechanical and electronic leak detection devices.
Durability: The durable, bolted construction of the ST1 is superior to the clamped-band construction pump, providing exceptional leak-free performance.
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 five minutes (versus 55 minutes for competitors). Additionally, the ST1 offers air-side interchangeability with SANDPIPER’s 1″ (SB1) for reduced inventory costs.
Trusted design: SANDPIPER’s original ADS is fully interchangeable, repairable and inline-serviceable. Other manufacturers frequently change ADS designs, creating issues with interchangeability, obsolete inventory and increased cost of ownership.
