Schenck Process Introduces CMD Airlock
The new CMD Airlock is designed for sanitary processes where inspection or system clean-out are required including food and pet food applications. The CMD is also a direct replacement for traditional square inlet Schenck Process MD airlocks in plant applications where sanitary requirements have increased, but the existing system does not allow for the use of a round inlet airlock.
Three different sized models come equipped with a square inlet and square outlet, along with seals and product contact surfaces that meet food safety requirements. The CMD is designed with a rail system consisting of externally mounted precision shafts, which are fixed to the tail side endplate on one end and are supported by special composite linear bearings pressed into the valve housing on the other. The endplate/rotor assembly can be unbolted from the housing, and the assembly can be pulled from the housing and drive coupling while still remaining rigid to the housing via the rail system. This simplifies removal and provides access to the internal valve cavity, rotor pockets and other product contact areas for quick and easy cleaning, according to the company.
Other product features include:
• Easy access to seals with rotor removed from endplate
• All stainless steel construction, with the exception of the endplate bearings
• Close clearance design that reduces overall leakage through the valve and minimizes pneumatic system losses
• Maximum 32 Ra finish on all wetted (product contact) parts
