Pros and cons:
+ Motor housing and impeller in stainless steel: resistant to chemically aggressive media
+ High head up to 25 m, flow rate up to 57.5 m³/h (CH436)
+ CH432 available in 230V and 400V, CH436 in 400V
+ All types also available explosion-proof (Ex)
+ Suitable for fixed installation with an automatic coupling system
− Free passage 10 mm: for waste water with coarse solids choose the CTP50 or CTP70
Stainless steel submersible pump for chemically aggressive media:
The HOMA CH432 and CH436 are stainless steel submersible pumps for chemically aggressive, relatively clean water with few solids: rinsing and process water, salt water, cooling water with additives and lightly contaminated commercial waste water. The motor housing and the open multi-channel impeller are of stainless steel. As a result the pump lasts far longer in aggressive water than a cast iron pump.
The difference with the CTP range lies in the application. The CH432/436 is built for capacity and pressure with water containing at most small particles (free passage 10 mm). The CTP50/70 is built for waste water with coarse solids and fibres. Which one do I need? If your water contains few solids but has to go high or far, choose a CH432/436. If it contains fibres or coarse solids, a CTP is better.
The CH432 delivers 26 - 30 m³/h at 11 to almost 19 m head and is available in 230V (W) and 400V (D). The CH436 achieves 52.8 - 57.5 m³/h and up to 25 m. For a potentially explosive zone, choose the Ex version. A pump like this is usually installed permanently in a sump with an automatic coupling system and guide rails.
Scope of delivery:
Pump with 10 m connecting cable, 5 m cable protection hose and free cable end. A control panel with motor protection and a coupling system are available as accessories.
