Stenner Pump 45MJH7A1S Dosing Pump Adjustable 1.1-22 GPD 100 psi

Description

Product Overview

The Stenner 45MJH7A1S dosing pump is engineered for high‑precision fluid delivery in demanding laboratory environments. With an adjustable head that provides a flow range from 1 to 22 gallons per day, the pump can be fine‑tuned to meet the exact dosing requirements of a wide variety of chemical, biological, and analytical processes. Its pressure rating of 100 psi ensures reliable operation even when dealing with viscous liquids or when higher back‑pressure is encountered. Constructed from corrosion‑resistant materials, the pump body and internal components are designed for long‑term durability, reducing the need for frequent replacement. The unit operates on standard 120 V, 60 Hz power, making it compatible with most laboratory power supplies. Package dimensions of 12.7 × 9.4 × 8.2 inches and a weight of 8.28 lb provide a compact footprint that fits easily on benchtops or within equipment racks.

Usage

This dosing pump excels in applications such as reagent preparation, sample dilution, chromatography solvent delivery, and controlled addition of catalysts in synthesis experiments. Researchers in chemistry, biochemistry, environmental testing, and pharmaceutical development rely on its consistent performance to achieve reproducible results. The pump’s adjustable flow capability allows users to switch quickly between low‑volume micro‑dosing and higher‑volume bulk dosing without changing hardware. Its 100 psi pressure capacity makes it suitable for use with pressure‑sensitive membranes, filtration systems, and closed‑loop recirculation setups. The pump can be integrated into automated workflows, communicating with laboratory control software via standard analog or digital interfaces, enabling precise timing and synchronization with other instruments. Whether operating in a temperature‑controlled incubator or a standard bench environment, the pump maintains accuracy and stability.

FAQ

What type of tubing is compatible with this pump?

The pump is designed to work with standard #7 Santoprene tubing, providing a 20‑foot length of 1/4″ black tubing for immediate use. Alternative tubing materials can be used as long as they meet the pressure rating of 100 psi.

Can the flow rate be changed while the pump is operating?

Yes, the adjustable head allows users to modify the flow rate on‑the‑fly without shutting down the pump, enabling real‑time adjustments during experiments.

Is the pump suitable for continuous operation?

Absolutely. The pump’s motor and internal seals are rated for continuous duty cycles, and the unit includes thermal protection to prevent overheating during extended use.

What warranty does Stenner provide?

Stenner offers a standard one‑year limited warranty covering defects in materials and workmanship, with the option to purchase extended coverage for up to three additional years.

How do I calibrate the pump for accurate dosing?

Calibration can be performed using the included flow‑metering chart or by connecting the pump to a calibrated gravimetric system. Detailed instructions are provided in the user manual, and Stenner’s technical support can assist with any questions.
