Abstract
A chemical injection pump for injecting chemicals into subsea system at depths up to 10,000 feet is described which uses a minimum of moving parts by employing an actuator, for instance a solenoid, to power a double acting actuator rod and plungers thereon. The pump would generate low pressures and low fluid volumes, but be more durable and reliable than conventional rotating pumps operating under subsea conditions.
