These high pressure piston pumps last longer and are more corrosion resistant than before. The manifold and crankcase have a new design. The u-shaped seal packings last 3 times longer than the previous design. The crankshaft length has been extended to 40mm, making these piston pumps better for coupling to electric motors. The ceramic pistons are attached to the piston guide using a nut which prevents accidental unscrewing. The NMT pressure pump range is now also available with nickel-plated head and plugs.
