Its 1.1kW coolant filled motor moves up to 650 litres of dirty water per minute and pushes to a 15 metre head, so it clears deep basements, long discharge runs and high demand chambers that would overwhelm smaller drainage pumps. A double channel impeller with 32mm free passage handles fibrous and contaminated wastewater without clogging, and 110V, 230V and 400V options cover everything from hire fleet work to fixed three phase installations.\u003c\/p\u003e\n\u003ch3\u003eWhat is the Semisom 635 pump used for?\u003c\/h3\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 6.0pt;\"\u003eThe Semisom 635 is the step up model for high volume wastewater and demanding drainage work.

The hydraulic end is cast iron for abrasion and impact resistance, while stainless steel motor components shrug off corrosion during years of submerged service. Heat from the larger 1.1kW motor is managed by a coolant filled design that allows sustained running without burnout, and a silicon carbide mechanical seal provides a hard wearing barrier between pumped liquid and motor. The double channel impeller geometry maintains hydraulic efficiency while passing 32mm solids.\u003c\/p\u003e\n\u003ch3\u003eWhy choose the Semisom 635?\u003c\/h3\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 6.0pt;\"\u003eThe Semisom 635 earns its place where downtime is expensive. Contractors and facilities teams pick it because it combines the flow of a much larger pump with a 21.3kg body that one person can still handle, and because its service intervals stay long even under continuous load. If you regularly find smaller drainage pumps running flat out and still falling behind, the 635 gives you the headroom to clear water faster and run the pump well within its comfort zone, extending its working life. Manual and automatic float switch versions let you specify it for attended site work or unattended duty in permanent chambers.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 6.0pt;\"\u003eDraining a smaller sump or cellar?
