Marine-grade paint system available for tropical-coastal bulk-terminal installations.<\/p>\n<\/div>\n<div class='eg-prod__feat'>\n<h4>Six Mounting Orientations<\/h4>\n<p>Factory-supported mounting positions B3, B6, B7, B8, V5 and V6.

Noise measurement in a semi-anechoic booth, sump-temperature rise monitored during run-in, and output-shaft backlash verified against catalogue specification. Test record is retained per serial number for five years, with certificate of conformity issued per shipment.<\/p>\n<\/div>\n<div class='eg-prod__feat'>\n<h4>Shared Inventory With NMRV Range<\/h4>\n<p>The internal worm-and-wheel gearing on the inch-series range is common with our NMRV metric-interface product.
