SPEAR PUMP
- Production of highly viscous oil & emulsions (up to 250 mPa·s) without reduction of flow rate.
- Pump type: specialized tubing
SPeaR differential pump is used for production of highly viscous oil and emulsions, prevents floatation of sucker rod string and improves pump efficiency.
APPLICATION
Production of highly viscous oil & emulsions (up to 250 mPa·s) without reduction of flow rate.
ADVANTAGES
- Continuous sucker rod string tension due to differential rod application;
- Pump pull-out without additional drain device;
- High-temperature modification up to 572°F (300°C);
- High-sand production modification (up to 2.5 g/l);
- Positive closing of standing valve.
BENEFITS
- Sucker rod string floatation is prevented;
- Higher pump efficiency.
