E G Danner Impeller Replacement for Drive Pumps Black Nylon 12776

Description

Product Overview

The E G Danner 12776 impeller replacement is a precision‑engineered component designed to restore the performance of magnetic drive pumps that rely on flexible impeller technology. Constructed from high‑grade black nylon, the impeller offers a balance of strength, chemical resistance, and low friction, allowing it to operate reliably at high flow rates of up to 1,800 gallons per minute. The part is sized to fit the MD18 and MD18B pump models, which are widely used in industrial cooling, water treatment, and process‑fluid circulation applications. Its compact dimensions—5.75 x 3.5 x 2 inches—and lightweight design (5.6 ounces) make it easy to handle, store, and install without the need for specialized tools.

Usage

This impeller replacement is intended for use in environments where reliable, continuous fluid movement is critical. Typical applications include HVAC chiller systems, chemical processing loops, boiler feedwater circuits, and large‑scale irrigation setups. The nylon material tolerates a wide temperature range and resists corrosion from most industrial chemicals, making it suitable for both indoor plant facilities and outdoor installations exposed to the elements. Users should verify that the pump they are servicing is a magnetic drive model compatible with the MD18 series before installation. Once installed, the impeller delivers smooth, vibration‑free operation, reducing wear on bearings and seals while maintaining the designed flow characteristics of the original equipment.

FAQ

What pump models are compatible with this impeller?

The 12776 impeller is compatible with E G Danner magnetic drive pump models MD18 and MD18B. It is also suitable for any flexible impeller pump that uses the same shaft dimensions and flow specifications.

Can this impeller be used with chemically aggressive fluids?

Yes. The nylon material is resistant to a wide range of chemicals, including many acids, bases, and solvents commonly found in industrial processes. However, for extremely aggressive chemicals, verify compatibility with the specific fluid composition.

How do I install the replacement impeller?

First, shut down the pump and relieve any pressure in the system. Remove the pump housing, extract the old impeller, and clean the shaft and housing interior. Insert the new nylon impeller, ensuring it seats evenly on the shaft. Re‑assemble the housing, restore power, and perform a brief run‑test to confirm proper operation.

Is there a warranty on this product?

The impeller comes with a standard manufacturer’s warranty covering defects in material or workmanship for a period of one year from the date of purchase.

Where can I find technical assistance if I encounter issues?

Danner’s technical support team is available via phone or email. Authorized distributors can also provide on‑site assistance, installation tips, and spare‑part recommendations tailored to your specific application.
