STACK™ Multipoint Injection Systems

A cost‑effective multipoint chemical injection solution, the STACK™ system enables delivery of chemical to multiple injection points from a single pump and controller, reducing complexity and operating cost. Designed for flexibility and performance in oilfield environments, STACK™ provides uniform treatment and reliable operation across a range of injection applications.

Overview

Features

Expandable from 2 to 15 injection points, easily added or removed in the field
All calibration and adjustments are done electronically, eliminating the need for mechanical setup or multi‑head pump setup
Independent rate control at each injection point with varying pressures and flow requirements
Single pressure transducer measures pressure status across all connected points
Stack Check performs automated quality checks to verify each injection point is functioning properly, with pressure measurements across all points viewable locally and remotely
Compatible with Sirius Connect remote monitoring systems (optional)
Fully in-house engineered CR Pro solenoid valve internals designed for superior chemical resistance

The Sirius pump speed varies between injection points depending on rates and cycle time
required, which provides equal chemical contact time between points.
