Round and Rectangular Dust-Gas-Air Duct Dampers

PGVU 292-80 Dampers

We are pleased to inform you that the team at LLC “SOYUZNASOSMASH” has developed a new product line: round and rectangular dust-gas-air duct dampers of the following types:

• PGVU 291-80
• PGVU 292-80
• PGVU 295-80
• PGVU 296-80
• PGVU 297-80
• PGVU 298-80

These dampers are designed to regulate and shut off dust-gas-air ducts in boiler installations at thermal power plants.

 Operating conditions:

• Maximum medium temperature: 400°C
• Maximum box pressure: 004 MPa

Rectangular dampers are manufactured in the following types:

• Single-shaft
• Double-shaft
• Triple-shaft
• Four-shaft
• Five-shaft
• Oversized models

Climatic categories:

• Moderate (U)
• Tropical (T)
• Installation category: 3 (per GOST 15150)

Dampers with remote-mounted bearings are marked MK-1046 with corresponding nominal diameter data.

Electric Arc Metallization (Thermal Spraying)

We apply protective and wear-resistant coatings to working surfaces of parts using activated electric arc metallization with powder wires.
 This method increases the performance of friction assemblies in machines and mechanisms.

Applications:

• Restores original dimensions of worn surfaces
• Strengthens friction surfaces (e.g., shafts, crankshafts, sliding bearings, guides)
• Restores bearing seats in housings and shafts

Benefits:
 Coatings provide specific properties to surfaces (e.g., heat resistance, thermal conductivity, defined friction coefficient), which may differ significantly from the base material.

Materials used for arc metallization include:

Example:
 Part: Crosshead rod of plunger pump ANT-55

• Surface: coated with wear- and corrosion-resistant metal powder wire
• Coating thickness: 0.4–0.5 mm
• Surface hardness: 60–65 HRC

Chemical semi-submersible pumps HPV, HPV(E)

Purpose

The submersible chemical pumps and pump units of the HPV and HPV(E) types are designed for transferring mildly aggressive and neutral liquids with a density not exceeding 1050 kg/m³, containing solid inclusions up to 0.2 mm in size with a volume concentration not exceeding 1.5%.

Currently, electric pump units are manufactured in two types:

•  HPV — for general industrial applications
•  HPV(E) — in explosion-proof design

Technical Specifications

•  D – flow path material: chromium steel 20X13L
•  55 – mechanical seal type: double mechanical seal
  
  

Ordering Note

Due to ongoing improvements and potential variations in electric motor suppliers, customers are strongly advised to confirm mounting and connection dimensions and required parameters when ordering units, using the recommended inquiry form.
