Frequently Asked

Popular Questions About IS 2298

?Which materials are designated for the pump barrel and plunger?▼

Per IS 2298, the pump barrel is constructed from Brass conforming to IS Alloy No. 2 of IS:407-1966. The plunger can be either Bronze, matching Sand casting grade 2 of IS:318-1962, or Brass, meeting Die casting grade 3 of IS:292-1961 or Hot forging grade 1 of IS:291-1964. The plunger rod is also made of Brass Alloy No. 2 (IS:407-1966) with a minimum machined diameter of 16 mm, ensuring durability, corrosion resistance, and smooth operation within the barrel.

?What are the requirements for the water jet throw distance and spray characteristics?▼

According to IS 2298, the pump should operate at a speed not exceeding 45 cycles per minute with the nozzle positioned at 1.5 meters above ground. For jet mode, the plain water stream must reach a minimum horizontal distance of 7 meters from the nozzle tip. In spray mode, the spray must resemble a gentle light rain with uniform distribution, having a width of at least 60 cm at 3 meters distance and 90 cm at maximum throw. The nozzle bore diameter is specified at 3 mm and is designed for swift switching between jet and spray modes, with the exit direction consistent for ease of aiming.

?How should the handle and stirrup be designed to ensure effective pump operation?▼

IS 2298 specifies that the stirrup should be fabricated from mild steel flats or rods and include a convenient foot rest for ease of use. It must be properly aligned with the pump barrel to maintain balance during operation. The handle should be D-shaped with an internal grip length of at least 200 mm and a grip diameter of 25 mm to provide a comfortable and secure hold, thereby improving operational efficiency and user comfort.

?What mandatory marking details must be present on the pump?▼

Each pump must be permanently marked with the manufacturer's name or trademark and the year of manufacture as per IS 2298 Clause 7.1. Additionally, the pump may bear the ISI Certification Mark, signifying compliance with Indian Standards under the supervision of the Indian Standards Institution, subject to licensing. This ensures clear identification, traceability, and quality assurance.

?What protective coatings are required for ferrous metal parts of the pump?▼

IS 2298 mandates that all exposed ferrous metal components must receive a primer coating followed by a paint layer colored fire red (Colour No. 536 as per IS 5-1961). The paint must comply with IS 2932-1964 standards. Additionally, the pump barrel should be protected with a 5 mm thick rubber sheath to provide extra resistance against corrosion and wear, enhancing the pump's longevity.
