lUsage GLB single screw PC pump is a new type of mechanical extracting equipment, applicable for the oil exploitation of low, high viscosity crude oil, high pour point oil, high wax-bearing oil, high sand and gas content oil, etc.

lFeatures It is one kind of widely used pump with the characters of less investment, high efficient, low-energy, easy for installation, operation and maintenance, stable and longtime operation.
1. The ground driving part runs smoothly with low noise.
2. We adopt a special and reliable mechanical sealing device, no bending stress points on the polish rod, no need maintenance and manual adjustment, ensures the safe oil production without leakages, and pollution-free of well site.
3. We adopt a special anti-reversion device, which ensures the reliable braking (brake torque > 4000N/m), start freely, easy and safe operation.
4. Diesel power driving device is designed for oil wells without power source.
5. We adopt variable frequency electrical device to realize the infinitely variable speeds control; excellent overload protection and energy saving. Electrical machine power: 11-22kw.

lWe have won 4 technology patents for PC pump R&D as follows.
1. A special type PC pump: ZL 20041 0035772.5
2. Wear resistant rod coupling: ZL 2005 2 0087768.3
3. Anti-wear protection device for oil pipe: ZL 2005 2 0087769.8
4. Anti-wear stabilizer for sucker rod: ZL 2005 2 0087770.0
