Stenner Pump Company replacement pump head QP255-1 — single-head replacement for precise chemical dosing, corrosion-resistant

When your existing metering pump needs a dependable head-only replacement, the QP255-1 provides a straightforward swap-in solution from Stenner Pump Company. Built to the brand's manufacturing standards, this single-head unit lets you refresh a worn or damaged head without replacing the entire pump assembly, saving time and cost while maintaining precise chemical dosing.

What does the QP255-1 pump head do for my dosing system?

The QP255-1 houses the internal components that move and meter liquid in a Stenner pump, restoring flow control and consistent stroke performance. Installing the head returns the pump’s ability to deliver accurate, repeatable doses of chemicals or additives.

• Replaces worn or damaged head components to recover accuracy
• Maintains factory-calibrated flow characteristics when paired with the original drive
• Compatible with the intended Stenner pump models that accept the QP255-1 head

How easy is it to install the single head replacement?

Installation is intended to be straightforward for technicians or experienced users familiar with Stenner pumps: the head removes and mounts with basic hand tools and follows the pump’s service instructions. Replacing only the head minimizes downtime and typically takes far less time than changing the entire pump.

• Designed for direct swap with the matching Stenner pump housing
• Fits standard tubing and fittings used by the original pump head
• Requires routine checks for tubing seating and clamp tightness after installation

What materials and quality features should I expect?

The QP255-1 is manufactured to Stenner’s quality standards, using corrosion-resistant materials suited for common chemical dosing fluids. The head-only approach focuses replacement on wear-prone parts while retaining serviceable components of the primary pump assembly.

• Constructed from durable, chemical-compatible plastics and elastomers
• Factory-tested to meet flow and stroke tolerances for consistent dosing
• Quality inspection ensures reliable fit and function with compatible pumps

When should I choose a head-only replacement versus a full pump?

If the pump drive and motor remain sound but accuracy or sealing is compromised, a head-only replacement like the QP255-1 is often the most economical choice. A full pump replacement is appropriate when multiple major components have failed or when an upgrade to capacity or features is required.

• Choose the QP255-1 when wear is limited to head components and tubing
• Opt for a full pump if the motor, gearbox, or electronic controls are defective
• Head replacement extends service life and lowers maintenance cost compared with full replacement

This single-head offering from Stenner Pump Company is aimed at maintenance technicians, facility managers, and contractors who maintain chemical feed, water treatment, or process dosing systems. If you already own a compatible Stenner pump and need to restore metering accuracy quickly and affordably, the QP255-1 provides a targeted, factory-standard replacement that keeps your system running without the expense of a full pump swap.
