LMI Pump PD051-832NI Peristaltic Pump 1.1 GPH 150 psi PVDF Head

Description

Product Overview

The LMI Pump PD051-832NI is a peristaltic metering pump engineered for precise fluid handling in demanding environments. Its core construction features a chemically resistant PVDF (polyvinylidene fluoride) head that tolerates aggressive solvents while maintaining dimensional stability under pressures up to 150 psi. The pump delivers a consistent flow of 1.1 GPH, making it suitable for low‑volume dosing, sample preparation, and continuous infusion tasks.

Designed with a 1/4 inch OD tubing interface, the unit includes a full set of accessories: a high‑quality injection valve for precise start‑stop control, a foot valve that prevents backflow, and a length of tubing pre‑cut to match the pump’s specifications. The compact footprint (approximately 6 inches tall) allows easy mounting on standard laboratory racks or integration into process panels without sacrificing performance.

Technical specifications are straightforward: model PD051-832NI, maximum pressure 150 psi, flow range 0.5‑2.0 GPH, and a PVDF head rated for continuous operation at temperatures up to 80 °C. The pump operates on a standard 12 V DC power supply, and its motor is protected by an internal thermal cutoff to extend service life.

Usage

In laboratory settings, the PD051-832NI excels at delivering exact volumes of reagents for chromatography, spectroscopy, and microbiology assays. Its low pulsation design minimizes shear stress on delicate samples, which is critical when handling cell cultures or enzyme solutions. The included injection valve enables rapid start‑stop sequences, allowing users to synchronize dosing with experimental timelines.

Industrial users appreciate the pump’s robustness for applications such as chemical dosing in water treatment, lubrication circuits in machinery, and feed delivery for bioreactors. The PVDF head resists corrosion from acids, bases, and solvents, while the foot valve ensures that the system remains primed even during power interruptions. The pump can be mounted in a cabinet or on a portable cart, providing flexibility for field service or on‑site testing.

FAQ

What types of fluids can the PD051-832NI handle?

The pump is compatible with most aqueous solutions, mild acids, bases, and organic solvents that are compatible with PVDF. Users should avoid fluids that exceed the temperature rating of 80 °C or that contain abrasive particles that could damage the tubing.

How do I install the tubing and valves?

Installation begins by securing the 1/4 inch OD tubing onto the pump’s inlet and outlet ports, ensuring a snug fit to prevent leaks. The injection valve is then placed in the line before the pump to allow precise control of start‑stop timing. Finally, the foot valve is installed downstream of the pump to maintain suction and prevent backflow when the pump is off.

Can the pump operate continuously for long periods?

Yes, the PD051-832NI is designed for continuous operation. Its motor includes a thermal protection circuit that shuts down the pump if temperatures exceed safe limits, and the PVDF head is rated for extended use without degradation.

Is the pump compatible with automated control systems?

The pump accepts standard 12 V DC input and can be interfaced with programmable logic controllers (PLCs) or microcontroller‑based systems using simple relay or transistor switching. This makes it easy to integrate into automated dosing rigs or process control loops.

What warranty does LMI Pump provide?

LMI Pump offers a one‑year limited warranty covering defects in materials and workmanship. During the warranty period, any faulty components are repaired or replaced at no cost to the customer, provided the product is used according to the supplied guidelines.
