Perspektiva LLC presents an overview of WARMIN sewer grinders—reliable solutions for wastewater treatment and blockage prevention. The manufacturer`s lineup includes three key models: WARMIN SCV, WARMIN SCVD, and WARMIN SCG. We`ll explain the differences between them, the applications they address, and how to choose the best option.

WARMIN SCV: A Vertical Grinder Without a Filter Drum

This model is designed to effectively grind solid waste in sewer systems and minimize the risk of blockages. Thanks to it, the treatment equipment operates reliably and without unscheduled shutdowns.

What can be crushed:

• textile materials (rags, ropes, hoses);
• glass products;
• paper and cardboard;
• wood and wooden elements;
• personal hygiene products;
• empty metal and plastic containers (bottles, cans);
• rubber and leather products;
• suspended particles and turbidity.

Optimal installation locations:

• in front of the sewage pump to protect the pumping station groups;
• after the waste screen, to crush floating waste;
• at the inlet of the waste incineration plant, to prepare waste for transportation and thermal disposal;
• inside the cleaning system pipeline, to break up solid inclusions in the sludge;
• in household waste collection areas, to recycle plastic, cans, batteries, and other waste.

Technical parameters:

• Capacity: 48,774 m³/h;
• Drive power: 1.5-5.5 kW.
• Price: from 1,750,000 rubles.

WARMIN SCVD: Vertical Crusher with Filter Drum

This model combines two functions: filtration and mechanical crushing. The operating principle is simple: the screen retains large objects, and the crushing unit converts them into safe fractions, after which the purified water continues to move through the system.

Why choose this model:

• reduces the likelihood of clogs that can lead to equipment failure;
• maintains stable operation of the entire treatment line;
• easily integrated into existing infrastructure (wells, pumping station channels);
• suitable for both modernization of existing facilities and for designing new sewer systems.

The application areas and list of processed materials are the same as the SCV model.

Specifications:

• performance: 45-1440 m³/h (depending on modification);
• Drive power: 2.2-4.0 kW;
• Price: from 2,200,000 rubles.

WARMIN SCG: flanged crusher with a prefabricated housing

This model is designed for intensive use in difficult conditions. The prefabricated housing makes installation and maintenance easier, while the flange connection ensures tightness and a long service life.

Key advantages:

• Modular design simplifies assembly and repair;
• Flange mounting ensures secure fixation in the system;
• High resistance to corrosion and wear;
• Adaptation to harsh conditions: aggressive environments, increased loads.

Where installation is particularly relevant:

• At large treatment facilities;
• In industrial sewer networks;
• In municipal systems with high load;
• during the reconstruction of obsolete facilities—as a modern replacement for worn-out equipment.

Model parameters:

• Capacity: 100–480 m³/h;
• Power: 4.0–7.5 kW;
• Cost: from 1,500,000 rubles.

How to decide

 

WARMIN SCV is a good solution if:

• the facility is small or medium in size;
• the wastewater does not contain many large particles;
• it is important to reduce initial costs;
• installation space is limited—the model has compact dimensions.

WARMIN SCVD is a better choice when:

• the wastewater contains a lot of large and fibrous waste;
• pre-filtration of the flow is required;
• peak loads are possible—the auto-reverse will protect the mechanism from jamming;
• the environment is characterized by increased corrosive activity (AISI 316 steel is resistant to aggressive conditions).

WARMIN SCG should be considered for:

• industrial facilities with complex wastewater;
• large treatment plants with high loads;
• facilities where equipment requires regular inspection and maintenance;
• conditions where tightness and durability are critical;
• projects with a horizontal installation scheme.

Selection Recommendations

• WARMIN SCV is a practical option for typical tasks: protection Pumps, household waste crushing, pipeline applications. Optimal for moderate loads.
• WARMIN SCVD is the choice for systems where inlet filtration is essential. Particularly effective with high concentrations of large particles.
• WARMIN SCG is the solution for severe conditions: industrial wastewater, aggressive environments, and the need for regular access to components. Suitable for large-scale treatment facilities.
