SandPIPER S Series Metallic Ball Valve Pumps

SandPIPER S Series Metallic Ball Valve Pumps

This metal Sandpiper® pump has wetted components in Aluminum, Cast Iron, Stainless Steel, and Hastelloy-C. They provide exceptional suction lift capacity for solids-free materials from low to high viscosity.
SandPIPER® Pumps are air-driven, double-diaphragm pumps. The simple design and operation offer many advantages over other types of pumps.
 
 Pumps abrasive and shear-sensitive materials
Low internal velocities move abrasives easily, with no damage to the pump. The gentle pumping action does not sheer fragile materials.
 
 Seal less, with no motors
These air-driven pumps, with no motors, seals or packing to leak, are environmentally friendly.
 
 Runs dry without damage
SandPIPER Pumps can run dry without damage, unlike other types of pumps.
 
 Optional porting
Many discharge porting options are available, including top, bottom, side and dual.
 
• Select top porting for thing liquids, or if entrained air could be a problem. 
• Select bottom porting for thick or solids-laden materials. 
• Select side or dual porting for specialized applications.
 
 Pumps viscous materials
Even heavy or solids-laden materials can be pumped. SandPIPER Pumps move everything from water to peanut butter.
 
 Self-priming
The pumps are able to dry prime under most suction lift and flooded suction conditions.
 
 Variable flow
Simply regulate the inlet air supply to adjust the pump flow from zero to maximum capacity.
 
 Deadheads against closed discharge
Excessive back pressure stops pump without damage. No need for expensive bypass systems or pressure relief valves. Pump simply stops operation until discharge opens.
Most diaphragm pumps are driven by compressed air. The directional air distribution valve and pilot valve, referred to as the “air end”, are located in the center section of the pump. Liquid moves through two manifolds and outer chambers of the pump, referred to as the “wet end”. 

Generally, check valves are located at the top and bottom of each outer chamber or on a common manifold. The two outer chambers are connected by suction and discharge manifolds. The pumps are self-priming.
 
No-Lube Air Distribution Valve
During operation, the Air Distribution Valve controls alternate pressurizing of one diaphragm, then the other. The Valve automatically transfers air pressure to the opposite chamber after each stroke. This provides alternating suction and discharge strokes, as the diaphragms move in parallel paths. Air valves require no lubrication. This is the preferred mode of operation. Clean, dry air will enhance pump performance.
 
Diaphragms
Flexible diaphragms are clamped at their outer perimeters, between the inner and outer chambers. The diaphragms are connected at their movable centers by a rod.
 
Check Valves
As fluid moves through the pump, check valves open and close. This allows each outer chamber to alternately fill and discharge. The check valves respond to differential pressures. Ball-type check valves can pass very small particles.
 
The Pumping Cycle
As the Air Distribution Valve directs pressurized air to the left diaphragm, the diaphragm is pushed outward. This is a discharge stroke, which forces liquid from the left outer chamber. Discharged liquid moves from the chamber, through an open discharge check valve, and exits the pump at the discharge manifold. 

The position of the discharge port can be top, bottom or side. As the left diaphragm is pressurized outward, the connecting rod pulls the right diaphragm inward on a suction stroke, which fills the left chamber with fluid. Liquid enters the pump at the suction manifold, moves through an open suction check valve and fills the chamber. At the end of the cycle, the Air Distribution Valve automatically shifts the air pressure to the opposite diaphragm, initiating another pumping cycle
