Semi Rotary Hand Pump

Semi Rotary Hand Pump

A semi-rotary hand pump is a manually operated pump used to transfer fluids such as water, oil, or diesel. It features a handle that moves in a semi-circular motion, typically around 180 degrees, which drives the pump mechanism. This action creates suction to draw fluid into the pump chamber and then expels it through the outlet. Semi-rotary hand pumps are often constructed from durable materials like cast iron or stainless steel to withstand various environmental conditions and fluid types.

These pumps are commonly used in applications where electric power is unavailable or impractical, such as in remote locations, agricultural settings, or during emergencies. They are appreciated for their simplicity, reliability, and ease of maintenance. The semi-rotary hand pump's design makes it efficient for transferring moderate volumes of fluid with minimal effort, making it a practical choice for various fluid handling tasks.

  • These capacities of pump given in table are calculated and based on a vertical lift of suction of 1m and a vertical delivery of 1m with full stroke at the rate stated.

  • A foot valve should be fitted when suction lift is more than 2m.

  • In case the Liquid is to be forced more than 4m above the pump, vertcal checkvalve on the delivery pipe is desirable .

Note :-
  1. Chemical pumps of non-ferrous Stainless Steel construction are also manufactured against specific enguiry.

  2. The maximum working pressure for these pumps are recommended for 2kg/cm approx
