Macewans Dinbloc End Suction Centrifugal Pumps

The Dinbloc is a close coupled centrifugal pump built to DIN 24255, offering back pull-out servicing and interchangeable parts for reliable, low-maintenance industrial pumping.

The Dinbloc is the close coupled version of the well-known Dinflow range, manufactured to the international DIN 24255 standard (the same standard often referenced as EN733). Instead of a separate pump and motor joined by a coupling, the Dinbloc’s impeller sits directly on an extended motor shaft, which means a smaller footprint, fewer alignment issues, and one less thing to go wrong on site. It’s built with a cast iron casing, a double shrouded, hydraulically balanced impeller with rear balancing vanes, and a stainless steel stub shaft and shaft sleeve as standard, so it’s set up to handle demanding day-to-day duty rather than just ticking a spec sheet.

What really sets the Dinbloc apart is how it’s designed to be lived with over the long haul. Every casing comes with a replaceable wear ring, the mechanical seal complies with the VDMA international dimension standard, and the back pull-out facility means the entire rotating assembly can be pulled for servicing without touching the pipework or casing at all. Add in the fact that many components are shared across the Dinbloc and Linebloc ranges, and you end up with a pump that’s genuinely cheaper and simpler to keep spares for. It’s a solid fit for liquid transfer, air conditioning and refrigeration systems, fire protection, drainage and irrigation, factory water supply, water treatment, and general industrial and waste water applications.

Key Features:

• Back pull-out design – service or replace the rotating element without disturbing the pipework or casing, cutting downtime during maintenance 
• Built to DIN 24255 – a recognised international standard, so dimensions and mounting are predictable and easy to specify around 
• Interchangeable components – shared parts across the Dinbloc and Linebloc range mean fewer spares to hold and lower long-term running costs 
• Robust standard construction – cast iron casing, stainless steel stub shaft and shaft sleeve, with a double shrouded, hydraulically balanced impeller for smooth, stable operation 
• Flexible materials and seal options – casing available in ductile iron, bronze or stainless steel, with impeller, wear ring and seal options to match the fluid you’re pumping 
• Wide operating range – handles temperatures from -20°C to 100°C and pressures up to 1000 kPa as standard, with options available outside these limits
