Review FLOJET Series Diaphragm Pump Head Upper Housing Kit fits QUAD

The Flojet 20404-002 4405 Quad Diaphragm Pump Head Upper Housing Kit is a crucial component for maintaining the optimal performance of your Flojet 4000 series diaphragm pump. Designed specifically for these pumps, this upper housing kit ensures a secure and precise fit, providing you with the reliability and efficiency you've come to expect from Flojet.

The upper housing is engineered using high-quality materials, including durable cast iron for the housing and corrosion-resistant stainless steel for the diaphragm caps. This design not only enhances the longevity of the component but also protects it from harsh environmental conditions and corrosive substances commonly found in various industrial applications.

The Flojet 20404-002 4405 Quad Diaphragm Pump Head Upper Housing Kit features four diaphragm caps, each designed to accommodate a single diaphragm. The diaphragms, which are not included in this kit, are responsible for transmitting the suction and discharge pressure to the pump's plungers. By replacing worn or damaged diaphragms and the upper housing, you can restore the pump's performance, minimize leaks, and prevent costly downtime.

To install the new upper housing, simply remove the old one by disconnecting the suction and discharge hoses, as well as the electrical connections. Once the old housing is removed, align the new upper housing with the pump body, and secure it using the provided fasteners. After installation, reconnect the hoses and electrical connections, and you're ready to resume pumping operations.

In summary, the Flojet 20404-002 4405 Quad Diaphragm Pump Head Upper Housing Kit is an essential component for ensuring the continued performance and efficiency of your Flojet 4000 series diaphragm pump. With its high-quality materials, secure fit, and easy installation process, this upper housing kit is an excellent investment for any industrial application where dependable and reliable pumping performance is critical.
