Sandshaver pump

Sandshaver pump significantly mitigates solids influence on operation of downhole equipment and increases its runlife.

Application

Pump is designed for operation in boreholes with high solids content (up to 8 g/l).

Advantages

Plunger with sharp edge cone top removes solids and salt deposits from barrel walls flushing
away with fluid flow delivered by pump;
Prevents solids accumulation in barrel-plunger clearance;
Sandshaver plunger can be installed in
pumps of any modification and size;

Benefits

Prevents pump clogging;
Reduced wear of barrel-plunger pair;
Higher well runlife;
