Item Overview for Blackmer MS4
The Blackmer MS4 pairs 4" stainless steel construction with a sliding vane pump layout suited to uncompromising chemical and severe-duty processes. ANSI Class 150 raised-face flanges tie the unit into existing piping without custom adapters. An internal relief valve protects the system from damaging pressure spikes. The bare-shaft build lets integrators match an existing drive or specify a new one. It also brings extended dry-run capability. As part of the MAGNES lineup, it shares parts and service procedures with the rest of the range. Rated for flows reaching 520 GPM, it holds output steady as line conditions shift. A single-ended keyed shaft turning right-hand drives Duravane vanes that adjust automatically and preserve capacity over a long service life. A sealless magnetic drive coupling and PTFE elastomers guard the drive end against leakage and swelling.
