Sure-loc

Sure-Loc riser pipe for installation of submersible pumps in water wells utilises an innovative pipe work mating arrangement. This makes the installation of borehole pumps much simpler, with less effort for the drilling contractor installing borehole pumps.

The uPVC pipe with a unique external rib feature locks the mating socket with guide ways to the external ribs on the riser pipe using nylon splines. This unique system of the ribs extruded pipe takes care of the torsion forces which will occur during pump start up and stopping.

The Sure-Loc system with self aligning ribs in the pipe and groves in the socket allow high strength nylon splines to be inserted forming a circumferential joint that locks the socket to the pipe and to make doubly "sure to loc" there is a second spline at each joint.

Combine the double spline with the key way coupling it over comes the need for grease on conventional screwed and socketed metal pipe and the repeated effort to tighten the pipe and fiddly torque control screws of other products and the subsequent requirement to torque in the screws.

Like wise to disassemble you simply have to remove the splines to unmake the joint.

Sure-Loc riser pipe is designed and manufactured to conform or exceed the performance requirements of ASTM specification D1785 schedule 80.

The initial cost of the Sure-Loc riser pipe combined with a long life (it will not rust) makes Sure-Loc the product of first choice for installation of submersible pump installations within water abstraction wells.

The system is also popular for temporary pump installations for clearance pumping, test pumping of water wells and for temporary dewatering systems on construction sites.

The Sure-Loc pipe work covers the range from 1.25" up to 4" and is economical compared to conventional metal riser pipes and heavy duty layflat hose currently available in the market.
