Universal Fit
The 'W' Series pump is a special adaptation of the standard progressive cavity pump. This pump design is modified with a wide-throat suction inlet which allows the media to enter the suction housing with ease and avoids clogging.
- Wide-throat suction inlet for easy media entry
- Avoids clogging at the suction point
- Built on the proven standard PC pump platform
- Universal fit across a broad range of applications
What the Hopper Design Solves
A standard suction inlet can struggle with certain feed conditions. The W Range's wide-throat hopper is purpose-built to solve exactly that.
Eases Media Entry
The wide-throat suction inlet gives thick, viscous, or bulky media a larger, easier path into the suction housing — reducing the resistance a standard narrow inlet would create.
Prevents Clogging
By avoiding restrictive geometry at the suction point, the hopper design significantly reduces the risk of bridging or blockages that would otherwise interrupt continuous operation.
Universal Application Fit
Because it's built on ROTOMAC's standard progressive cavity pump platform, the W Range slots into the same broad range of applications — just with better feed handling.
Built for Difficult Feed Conditions
When a standard suction inlet isn't enough, the W Range's hopper design steps in.
Wide-Throat Inlet
Larger suction opening for easier media entry, even with bulky or viscous feed.
Anti-Clogging
Reduces bridging and blockages at the suction point for uninterrupted operation.
Universal Fit
Built on the standard PC pump platform, fitting the same broad range of applications.
