BQY/K10-15 Outer Diameter 140mm NBR&F46 Diaphragm for QBY-K / QBY / QBK

Product Description:

These premium replacement diaphragms are specially engineered for QBY/K series pneumatic diaphragm pumps. Crafted from sturdy elastomers and advanced engineering plastics, they offer reliable performance across a range of applications.

Customers can choose from three distinct material options to suit specific needs. NBR (nitrile rubber) is ideal for general-purpose use involving oil and water. F46, a modified PTFE fluoropolymer, is tailored for handling aggressive chemicals. For applications demanding the highest chemical resistance and purity, imported PTFE (polytetrafluoroethylene) diaphragms are available.

The diaphragms come in various sizes, with outer diameters ranging from 140 mm to 450 mm. They feature standard bolt hole patterns, such as the 10-hole configuration, as well as plain-edge designs to accommodate different pump models. Each unit is precision-molded to guarantee an excellent seal, extended flexibility, and reliable pumping efficiency even under challenging industrial conditions.

These replacement diaphragms are perfect for restoring worn or damaged parts in pumps used for slurry, chemical processing, food production, and mining transfers, ensuring continued optimal performance.

Features:

We offer a variety of materials tailored to meet different operational needs. Our NBR (Nitrile) option provides excellent resistance to oil, fuel, and water, performing reliably within temperatures ranging from -30°C to +100°C.

For applications requiring superior chemical resistance, the F46 (Fluoropolymer) material is an ideal choice. It withstands acids, solvents, and strong oxidizers effectively, with a temperature tolerance between -20°C and +150°C.

Additionally, we supply Imported PTFE, renowned for its exceptional non-stick properties and inertness to nearly all chemicals. This material is particularly suitable for food and pharmaceutical applications due to its high purity and safety standards.

Our products are available in diameter sizes ranging from 140 mm up to 450 mm, allowing compatibility with a wide range of pump models.

Regarding mounting options, components come with a standard 10-hole bolt pattern for larger sizes or a plain-edge design without holes, perfect for clamp-style installations.

Engineered for durability, the materials possess high flexural fatigue resistance, enabling them to endure millions of operational cycles without cracking.

Precision molding techniques are applied to ensure a perfect fit and reliable sealing against pump housings, enhancing overall performance.

These components are fully interchangeable and serve as direct replacements for several pump series, including QBY/K10-15, K25-40, K50-65, and K80-100.

Choosing our products is a cost-effective solution that can extend pump service life and minimize downtime, thereby improving operational efficiency.

For specialized needs, blue polyether (polyurethane) versions are available, offering enhanced abrasion resistance and easy identification through color-coding.
