M+B Fluid Technology GmbH, Andreas Viereck The electric barrel pump Principle of the barrel pump A barrel pump is a vertical centrifugal pump. At the lower end of a drive shaft (e.g. made of stainless steel or Hastelloy), a rotor/impeller rotates at typical speeds of...
M+B Fluid Technology GmbH, Andreas Viereck The difference between NPT and BSP threads The main difference between NPT and BSP threads lies in the thread angle (NPT: 60°, BSP: 55°) and in the shape of the thread profile (NPT: conical, self-lubricating; BSP: parallel for internal threads and k...
M+B Fluid Technology GmbH, Andreas Viereck Difference between Camlock couplings stainless steel according to MIL 59326A and DIN standard In general, all Camlock couplings are compatible with each other. Whether according to DIN or MIL standard, regardless of PP brass, aluminium or stainless steel. All couplings can be combined with each other. (Single...
M+B Fluid Technology GmbH, Andreas Viereck Storz couplings forged or cast? Forged Storz couplings are superior to cast ones, as they have higher strength, no air inclusions, and greater reliability. Feuer-Vogel GmbH advises against the risk of brittleness...
M+B Fluid Technology GmbH, Andreas Viereck What is the difference between BSPP, BSPT and R threads? The main difference between BSPP and BSPT threads lies in their shape and sealing method: BSPP (British Standard Pipe Parallel) is a parallel (cylindrical) thread that has an additional di...
M+B Fluid Technology GmbH, Andreas Viereck How do I determine an inch thread? How do I determine an inch thread? Determining an inch thread often causes confusion - especially because the inch specifications do not correspond to the actual millimetre measurements. Many think that a 1"-G...
M+B Fluid Technology GmbH, Andreas Viereck How do I determine a barrel thread? How do I determine a coarse thread on a plastic or metal barrel? Here's how to measure correctly. The easiest way to determine a thread is to unscrew the insert or closure and then...
