Tabular data reflects single head plunger pump with 15:1 drive and 1,750 RPM motor in vertical orientation.
Flow rate minimums are accurate for regular pump operation. Use within 10-100% of flow rate maximums and fluid viscosity up to 10cP to achieve API accuracy, linearity, and repeatability guidelines. Tabular data should be used for quick reference only. See performance curves for accurate pump selection.
Series SLA Leakless Plunger Pump: Frequently Asked Questions
What is the CheckPoint Series SLA?
The Series SLA is an electric leakless plunger chemical injection pump with a robust casing and variable eccentric drive designed for harsh conditions. It delivers up to 50.87 USG/H (192.56 L/H) and injects into pressures up to 13,500 PSIG (931 BARG).
What does leakless mean on the Series SLA?
The SLA plunger design is engineered to prevent chemical leakage to atmosphere at the plunger seal, which protects personnel, the environment, and the drive. This makes it well suited to hazardous or toxic chemicals and to sites with strict emissions requirements.
Does the Series SLA meet API 675 accuracy guidelines?
When operated within 10 to 100 percent of the maximum flow rate with fluid viscosity up to 10 cP, the Series SLA is designed to achieve API accuracy, linearity, and repeatability guidelines. Contact CheckPoint for compliance documentation for a specific configuration.
Can the Series SLA be mounted horizontally or vertically?
Both. Published performance data covers vertical and horizontal orientations, with dimensions of approximately 16.9 x 15.4 x 18.5 inches vertical and 12.7 x 17.9 x 18.5 inches horizontal, and weights from 76 to 88 lb (34.5 to 39.9 kg).
What plunger sizes does the Series SLA offer?
Plunger sizes from 3/8 inch (up to 13,500 PSIG, 3.18 USG/H) through 1/2 inch (7,600 PSIG), 3/4 inch (3,300 PSIG), 1 inch (1,900 PSIG), and 1-1/2 inch (800 PSIG, 50.87 USG/H). Tabular data is based on a 15:1 drive with a 1,750 RPM motor.
What applications suit the Series SLA?
High pressure continuous chemical injection where accuracy and containment matter: methanol and MEG hydrate inhibition, corrosion and scale inhibitor injection, and other critical dosing on wellheads, pipelines, and process plants.
