FORWATER MH-90S-600 Stainless Steel Multistage Centrifugal Pump 0.45 kW

FORWATER MH-90S-600 Stainless Steel Multistage Centrifugal Pump (0.45 kW output)

Compact stainless steel multistage boosting — 22 m of clean-water head.

The MH-90S-600 is the entry model of the FORWATER MH stainless steel multistage centrifugal series. Every water-contact part is 304 stainless steel, so the pump protects water quality as well as delivering steady pressure — a common requirement in domestic, food-adjacent and light industrial supply.

Key Features

• 304 stainless steel water-passing parts — protects water quality
• Compact, space-saving structure — fits service cupboards and plant rooms
• Power delay start — softer electrical and hydraulic start-up
• Water shortage protection — protects the pump from dry running
• Castings with electrophoresis process — anti-corrosion and rust prevention
• Insulation grade F, protection class IPX4

Frequently Asked Questions

What does "multistage" mean for me? Several impellers in series produce higher pressure from a compact body — more head per centimetre than a single-stage pump.

Does it protect itself if the water runs out? Yes — the MH series includes water shortage (dry-run) protection and power delay start.

Is it suitable for drinking-water supply? The water-passing parts are 304 stainless steel, which is widely used in potable-water applications. Confirm your local requirements with your installer.
