VX-80-1,5 - 400 V submersible pump with cutting impeller
The IBO VX-80-1,5 submersible pump with a single-channel open impeller is a three-phase 400 V industrial unit designed to pump raw sewage containing fecal matter, as well as dirty water. The impeller is equipped with a blade that cuts up fibrous contaminants, while the dual, independent sealing system and oil chamber protect the motor from water even if one of the seals is damaged.
Who it's for
-
Industrial plants and wastewater treatment plants – the cutting blade impeller handles fibrous contaminants, reducing the risk of blockages in the system.
-
Sewage pumping stations and fixed installations – the option to install the pump on guide rails with a foot coupling makes it easy to replace without emptying the tank.
-
Companies installing large systems – the 400 V three-phase power supply makes it easy to integrate the pump with distribution boards and control cabinets.
-
Municipal utilities handling high volumes of sewage – the dual sealing system and oil chamber protect the motor during continuous operation.
Applications
The VX-80-1,5 submersible pump with a single-channel open impeller is designed to pump raw sewage containing fecal matter, as well as dirty water. The impeller is equipped with a blade that cuts up fibrous contaminants, reducing the risk of blockages in the system. However, the fibers being cut should not exceed 80% of the pump outlet diameter.
The unit operates in a vertical position, with a maximum pumped liquid temperature of 40°C and water pH ranging from 6 to 10. The VX-80-1,5 400 V submersible pump achieves a head of up to 13 m / 17 m at a flow rate of up to 1000 / 1360 l/min.
Features of the VX-80-1,5 pump
The pump has a cast-iron construction, with a cast-iron motor housing, body and impeller. The shaft is made of AISI 304 stainless steel, so it does not corrode during constant contact with sewage and keeps the impeller precisely aligned throughout its service life.
The impeller-side seal uses a silicon carbide/silicon carbide arrangement - a hard material pairing with high abrasion resistance and a low coefficient of friction, extending seal life during constant contact with contaminated water. A separate second seal on the motor side operates submerged in an oil chamber, using a carbon/ceramic arrangement and cooled and lubricated by oil. This dual sealing system protects the motor from water even if the first seal is damaged. Cast-iron feet bolted to the underside of the housing keep the pump at the right distance from the ground, reducing the risk of the inlet becoming clogged.

Frequently asked questions (FAQ) – VX-80-1.5 submersible pump
What contaminants can the VX-80-1.5 pump impeller handle?
The open impeller with a cutting blade cuts fibrous contaminants in wastewater, provided their length does not exceed 80% of the pump outlet diameter. This helps reduce the risk of clogging in installations handling raw wastewater containing fecal matter.
What is the oil chamber and double seal for?
The double mechanical seal system protects the motor from water even if the first seal on the impeller side is damaged – the second seal operates submerged in the oil chamber on the motor side, providing an additional layer of protection.
How does the VX-80 pump differ from the WQ 65/80 series?
The VX-80 pump uses an open single-channel impeller with a cutting blade that cuts fibrous contaminants in wastewater. The WQ 65/80 series has a closed, two-channel impeller without a cutting function, designed for higher flow rates in wastewater without an excess of long fibers.
Is the VX-80-1.5 pump suitable for my installation?
The pump is suitable for installations where wastewater contains fibrous contaminants that need to be cut before pumping, as well as installations with a three-phase power supply. We encourage you to contact our technical department if you have any questions.
Where can I buy the VX-80-1.5 submersible pump?
Dambat does not sell directly. The VX-80-1.5 pump is available from trade partners, plumbing wholesalers, and authorized online distributors.
What warranty terms apply to the VX-80-1.5 pump?
IBO – 24 months (2 years) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
