Need industrial flow control but can't decide between a full process pump and a pump-drive USB kit? These two purchases sit on opposite ends of the pumping spectrum. The PumpWorks 101-00145-0000 PWA 2x3x8 is a complete centrifugal process pump built to ANSI/ASME B73.1, while the Masterflex L/S Digital Process Pump Drive Cinch 30-3006-6 Connection USB Kit is a compact connection accessory for a Masterflex drive.
Both are new items, and both are made in the US. But the $3,234.89 price spread between them tells you these aren't competing versions of the same product-they're answers to different flow-control problems.
Quick verdict: If your application needs a pump that moves fluid through flanged piping right now, the PumpWorks PWA 2x3x8 is the clear choice. If you already have a Masterflex L/S Digital Process Pump Drive and just need the Cinch USB connection kit, the Masterflex component is the low-cost, task-specific buy.
| Product | Listed Price | Price Bar | What You're Buying |
|---|---|---|---|
| PumpWorks 101-00145-0000 PWA 2x3x8 ANSI B73.1 Centrifugal Process Pump | USD 3,324.45 | Complete process pump with 2-inch discharge, 3-inch suction, carbon steel casing, and 316SS shaft | |
| Masterflex L/S Digital Process Pump Drive Cinch 30-3006-6 Connection USB Kit | USD 89.56 | USB connection kit for a Masterflex L/S Digital Process Pump Drive |
Where the PumpWorks wins: The PumpWorks is the only standalone pump in this pairing. It's configured as a 2x3x8 with a 3-inch suction, 2-inch discharge, and 8-inch maximum impeller diameter. The ANSI/ASME B73.1 standard means it follows a recognized horizontal end-suction process pump layout. Its carbon steel (WCB) casing, 316 stainless steel shaft, threaded carbon steel impeller, aramid fiber gasket, Teflon mechanical seal, and oil-bath bearing lubrication with ISOMAG magnetic bearing isolators add up to a serious piece of process equipment.
Where the Masterflex wins: The Masterflex kit is dramatically less expensive and much simpler in scope. It's described as a Cinch connection USB kit for a Masterflex L/S Digital Process Pump Drive, and the listing makes clear it's a component rather than a complete pump. For someone repairing or completing an existing Masterflex drive setup, the low entry price is the main advantage-no big capital outlay just to get a connection piece.
PumpWorks 101-00145-0000 PWA 2x3x8 ANSI B73.1 Centrifugal Process Pump

This is the heavy lifter of the two. It's a new, US-made pump built to ANSI/ASME B73.1 with a 3-inch suction, 2-inch discharge, and 8-inch maximum impeller diameter. The carbon steel casing and 316 stainless steel shaft are paired with a Teflon mechanical seal and oil-bath bearings using ISOMAG magnetic bearing isolators-details that point toward continuous process service. Choose it when your flow-control task requires a complete centrifugal pump with flanged connections rated for 150# flat-face piping. The trade-off is the price: at USD 3,324.45, this is a major purchase, and you'll need to confirm your piping matches the 2-inch discharge and 3-inch suction connection sizes before committing.
Masterflex L/S Digital Process Pump Drive Cinch 30-3006-6 Connection USB Kit

If your pumping setup already centers on a Masterflex L/S Digital Process Pump Drive, this new, US-made USB connection kit is the low-cost add-on. The listing describes one Cinch connection USB kit, and it isn't a custom bundle or modified item. The reason to pick this is the USD 89.56 price-a very small outlay compared with the PumpWorks pump. But the limitation is scope: this is a connection component, not a pump or drive, so it won't move fluid on its own. It only makes sense as a piece of a larger Masterflex-based flow-control system.
Final choice by use case: Choose the PumpWorks 101-00145-0000 PWA 2x3x8 if you need a complete ANSI B73.1 centrifugal process pump ready to handle flanged piping and process fluids. Choose the Masterflex L/S Cinch USB kit if you already own a Masterflex L/S Digital Process Pump Drive and need the USB connection piece at the lowest possible price.
