Pipe Surge and Water Hammer Apparatus
Product Code : LSK-HAP-10578
Pipe Surge and Water Hammer Apparatus (SKU LSK-HAP-10578) is a self-contained, closed-circuit rig with two test sections: one shows mass oscillation in a surge shaft, the other the sharp pressure rise of water hammer when a valve closes. Hydraulics and fluid mechanics labs in civil and mechanical engineering colleges and polytechnics use it. Science Lab Supplies manufactures the rig at its Saha, Ambala works (Plot 448, HSIIDC Industrial Area, India) and quotes each college, contractor or distributor directly.
Specifications
Every listed dimension, sensor and utility of the water hammer rig has its own table row. In short, water passes from a constant head tank through a 3 m stainless steel test pipe into a measuring tank, a clear acrylic surge shaft and 4–20 mA sensors capture each transient, and an interface logs the data to a computer.

Applications and Experiments for the Water Hammer Apparatus
Students close the gate valve and watch transient behaviour develop: a pressure spike in the water hammer section and a rising, oscillating level in the surge shaft. Logged data links these runs to pipeline and penstock topics in B.Tech and diploma hydraulics, making it useful engineering lab equipment in India.
- Demonstrating the surge phenomenon in a pipe and the oscillatory characteristics of a surge shaft.
- Recording water hammer pressure after valve closure with the 0–7 bar sensor.
- Relating the results to the Hydraulic Ram Pump, which uses the water hammer effect to lift water, after steady-flow losses have been studied on Friction Loss In A Pipe.
Standard Scope of Supply
The rig comes with both test sections, head, measuring and sump tanks, the circulating pump, valves, pressure, level and flow sensors, the interfacing unit with data-logging software, a control panel with on/off switch and mains indicator, and an English manual. The computer, water supply and floor drain are provided by the user.
Packing, MOQ and Lead Time
Whether you need one rig for a hydraulics lab or several for a new campus, the quotation states packing, delivery time and price for that number, and other pipe-flow apparatus or a hydraulics bench from the same range can be added to it.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Malaysia, Peru, Egypt, Iraq, Nigeria and Kenya. Questions on sensors or software go to the contact page; to combine the rig with other apparatus, use the enquiry cart; for tenders, the lab tender page sets out the process.
Frequently Asked Questions
What is the difference between pipe surge and water hammer?
Water hammer is the rapid pressure wave that follows sudden valve closure; pipe surge is the slower mass oscillation of water in a surge shaft. This rig has a separate test section for each.
Is a computer supplied with the apparatus?
No. The interface and software are included, but a computer (P-IV class with Windows 7, MS Office and a free USB port) is listed as a user-provided utility.
Is Science Lab Supplies the manufacturer or a trader?
The manufacturer: this apparatus is fabricated at the company’s own plant in Saha, Ambala, India, and every quotation for it is issued directly by that factory.
