A double volute casing has two single volutes 180° apart; Total throat area of two volute is same as the throat area of a comparable single volute; Double volute significantly reduces the radial load problem of the single volute pump; Hydraulic performance of a double volute pump is nearly the same as that of a single volute; Double volute pump is around 1-1.5 point less efficient at .
Screw conveyors are essential equipment in various industries, used for transporting materials horizontally, at an incline, or vertically. One crucial aspect of screw conveyor design is determining the appropriate length of the conveyor. The length of a screw conveyor can significantly impact its performance, efficiency, and overall functionality. In this article, we will explore the factors that influence screw conveyor design and capacity, as well as provide insights into screw conveyor length considerations.
Capacity is defined as the weight or volume per hour of a bulk material that can be safely and feasibly conveyed using a screw conveyor. Screw conveyor diameter is determined by multiple factors including capacity. Calculate required capacity in cubic feet per hour (ft 3 /hr).
Factors Influencing Screw Conveyor Design
Several factors play a critical role in determining the design of a screw conveyor. These factors include:
# 1. Material Properties
The type of material being conveyed is a primary consideration in screw conveyor design. Factors such as the material's bulk density, particle size, flowability, and abrasiveness can influence the selection of the screw conveyor type, size, and length.
# 2. Conveyor Capacity
The required capacity of the screw conveyor is another crucial factor in its design. The capacity is determined by factors such as the material flow rate, conveyor speed, and the size and pitch of the screw. A higher capacity requirement may necessitate a longer screw conveyor to accommodate the desired material throughput.
# 3. Operating Conditions
The operating conditions, including the environment in which the screw conveyor will be used, temperature variations, and the presence of any corrosive or abrasive materials, can impact the design specifications, including the length of the conveyor.
Screw Conveyor Capacity
The capacity of a screw conveyor refers to the maximum amount of material that the conveyor can transport in a given time period. The capacity of a screw conveyor is influenced by several factors, including:
# 1. Screw Conveyor Diameter
The diameter of the screw plays a significant role in determining the conveyor's capacity. Larger diameter screws have a higher capacity as they can accommodate more material. The diameter of the screw is typically specified in the screw conveyor size chart provided by the manufacturer.
# 2. Screw Conveyor Length
The length of the screw conveyor directly affects its capacity. A longer conveyor allows for more material to be transported, increasing the overall capacity of the system. However, the length must be balanced with other design considerations to ensure optimal performance.
# 3. Pitch and Speed of the Screw
The pitch of the screw, which refers to the distance between the flights, and the rotational speed of the screw also impact the conveyor's capacity. A larger pitch or higher speed can increase the material throughput but must be carefully selected based on the material properties and operating conditions.

According to Mahoney, from the 1920s to the early-1940s, Class B pumps (400 gpm to 600 gpm) dominated the fire pumper market. As the 1940s faded, the most common pump size had become the Class A .
