Type 5 All Non-Metallic, Non-Replaceable Diaphragm Seals
For wastewater and chemical feed applications, as well as applications with corrosive media. Constructed of corrosion-resistant PP glass fiber reinforced upper housing and PP, PVC or PVDF lower housing. PTFE-coated EPDM diaphragms are standard on all assemblies. Designed for applications such as wastewater and chemical feed, deionized water systems, and reverse osmosis systems.
Type 12 Sanitary, Clamped-Style, ASME-BPE, Non-Replaceable Diaphragm Seals
Features a flush mount diaphragm and all welded construction, ideal for food and beverage, pharmaceutical and sanitary markets. Wetted parts and all welded housing are constructed of 316 Stainless Steel for greater strength and durability. Clamped connection allows ease of installation and removal of seal for maintenance and cleaning. Wetted materials polished to Ra 32 or better. Applications include water and wastewater, chemical and petrochemical, and food and beverage.
Type 20 Front Flush, Non-Replaceable Diaphragm Seals
Designed for applications requiring an NPT male threaded process connection and with a flush diaphragm. Flush diaphragm construction prevents clogging and process material build-up. Constructed with a 316 Stainless Steel housing and diaphragm for strength and durability. Ideal for chemical and petrochemical, pharmaceutical, and pulp and paper applications.
Type 25/25H Standard and Elevated Pressure, Non-Replaceable Diaphragm Seals
Utilize an all welded, all metallic housing design to eliminate potential leak paths. For use with transmitters and gauges with dial sizes of 2-1/2" and smaller. Housing and diaphragm offered in a variety of materials to suit most applications. Applications include water and wastewater, oil and gas, and chemical and petrochemical.
Type 29 High Volumetric Displacement, Non-Replaceable Diaphragm Seals
An off-line seal with a threaded connection and all welded, all metallic housing design that does not utilize an o-ring or gasket. Designed with a larger diameter diaphragm for higher displacement capability. A variety of upper and lower housing and diaphragm materials are available to suit most applications. An optional flushing port is available to clean wetted areas and prevent process media build up. Ideal for applications such as water and wastewater, oil and gas, and chemical and petrochemical.
Type 30/30H Standard and Elevated Pressure, Bolted, Non-Replaceable Diaphragm Seals
Utilizes an all-metallic diaphragm welded to the upper housing to allow field replacement of the lower housing while maintaining continuity of the measuring system. A wide variety of instrument and process connections are available. An optional flushing port is available to clean wetted areas and prevent process media build up. Applications include water and wastewater, oil and gas, and chemical and petrochemical.
Type 30L Reduced Pressure, Non-Metallic Lower, Bolted, Non-Replaceable Diaphragm Seals
Designed for applications where typical metallic lower housings cannot withstand process media. Utilizes an all-metallic diaphragm welded to the upper housing to allow replacement of the non-metallic lower housing while maintaining continuity of the measuring system. Applications include oil and gas, chemical and petrochemical, agriculture, and pulp and paper.
