Handpumps Sectional Committee, ME 27

FOREWORD

This Indian Standard (Parts 1to 8) was adopted by the Bureau of Indian Standards, after the draft finalized by theHandpumps Sectional Committee had been approved by the Mechanical Engineering Division Council.

The need for deepwell handpumps of proven design to ensure interchangeability of components, having a longworking life and requiring minimum possible maintenance, had resulted in initiation of work to bring out astandard on the subject. As a result of the combined efforts made in this direction by various voluntaryorganizations, government agencies and reputed manufacturers as well as by UNICEF, a standard on deepwellhandpumps IS 9301 ‘Deepwell handpums — Specification’ was first issued in 1979. This type of deepwellhandpump is also popularly known as India Mark II handpump.

The first revision of IS 9301which was issued in 1982 was taken up in order to bring the standard in line with thethen manufacturing practices. A number of modifications were incorporated in the first revision, of which thefollowing were important:

a) The requirements of galvanizing was incorporated so that the pumps were tlee of rust for longer periods.

b) The ‘performance test’ given in the 1979 version was designated as the ‘type test’ and a new clause on‘routine test’ was included.

The second revision of IS 9301 was brought out in 1984 in order to bring the standard in line with the techniquesthen prevalent for the manufacture of deepwell handpumps. The following were some of the important changesmade in the second revision:

a)

b)

c)

d)

e)

o

g)

Tolerances on some of the dimensions had been changed, and specified on the basis of IS 919 (Rut 1): 1963‘Recommendations for limits and fits for engineering: Part 1 General engineering @rst revision)’.

Stainless steel had been specified as the material for manufacturing handle axle.

Solid triangular gusset at the top and bottom of the handle bracket were provided.

Connecting rods and plunger rod had been provided with hexagonal couplers in place of locknuts.

40 mm tank spout had been specified in place of 32 mm one in order that the tank is immediately clearedof the water and there is no undue splash.

Rear two stand legs at 80° had been specified in place of 120° in order to increase the stability of thepump.

Painting had been deleted as an anti-corrosive treatment for steel components.

The third revision of IS 9301 was brought out in 1990 to bring the standard in fine with the then prevailingmanufacturing practices. The following changes were made in the third revision: “

Upper valve modified in two parts for eliminating failure due to unscrewing of upper valve seat retainer.

Welding of stainless steel components specified.

Critical dimensions, in the figures, identified for inspection purposes.

Nitrile cup washers had been introduced to improve life of the pump. However, leather cup washers wasintended to be phased out in two years time.

Bearing housing had been modified for minimizing distortion due to welding.

Third plate had been introduced for easy maintenance.

n) Type test had been deleted.

p) Stroke length had been increased.

q) Discharge requirement increased from 12.0 litre to 15.0 litre during discharge test.

r) Height of water tank increased from 129 mm to 154 mm.

Since the development of deepwell handpump, considerable progress has been made in its refinement. Efforts ofdifferent organizations and individuals including UNICEF, UNDP/World Bank Water and Sanitation Programmecontributed to design improvement, increased reliability and simplified maintenance.

The outcome of these developmental efforts was the emergence of a handpump designated VLOM — Village -Level Operation and Maintenance deepwell handpumps with open top cylinder. Design of this handpump issuch that the most common repair can be done by local mechanics. Modifications incorporated in this pumpsimplify maintenance procedure and reduce maintenance cost. The basic difference of this pump with deepwellhandpump (IS 9301) is that this pump has open top cylinder which facilitates pulling out of plunger assemblyand check valve assembly from the cylinder without pulling out the riser main and the cylinder.

This type of pump is popularly known as India Mark 111deepwell handpump and the relevant Indian StandardIS 13056 ‘Deepwell handpumps (VLOM) — Specification’ was issued in 1991,

The initial additional investment and installation depth limitation had beqn identified as main constraints inadoption of VLOM pumps. Moreover increased static load of riser main and weight of water column alsoresulted in observation of shearing of riser pipe near the riser pipe holder in few cases. As a result, a smaller sizecylinder (50 mm) was developed to overcome such problems experienced in 65 mm cylinder. Afier successfidtrials of 50 mm cylinder for over 5 years, these were ultimately included in VLOM pump specification(IS 13056). The major advantages over 65 mm cylinder were the lower capital cost, reduced static load andweight of water column to support and ease in installation and maintenance.

As in some of the states, the static water level had gone below 40 m, the existing deepwell handpumps (IS 9301)were difficult to operate and therefore it was felt necessary to design a separate pump for such purposes. Theobjective set out for the development of the extra deepwell handpumps were:

a) to design a system, which allows the use and interchangeability of most of the components with theexisting deepwell handpumps (IS 9301), and

b) to keep operational efforts within reasonable limits.

This led to the emergence of India Mark H extra deepwell handpump and the relevant Indian Standard IS 13287was issued in 1992.

After publication of these handpump standards, based on the experience gained during manufacture, inspection,installation and their maintenance, six amendments were issued to India Mark 11handpump — Specification[1S 9301:1990 (third revision)]. Similarly 6 amendments were issued to VLOM pump — Specification(1S 13056: 1991) and 4 amendments were issued in Extra deepwell handpump — Specification (IS 13287: 1992),to keep abreast with the technological changes.

Over the years, demand had been generated to prepare a comprehensive document to cover all the three types ofhandpwnps for lifling water from deep set bore wells, water depth ranging from.,20m to 90 m. Further the needwas also felt to incorporate the requirements of components and special tools used in repair/maintenance of thesepumps to enable the users/purchasers to procure components as per this standard to ensure quality andinterchangeability. As a result, this Indian Standard has been formulated amalgamating following Indian Standards:

1S No. Title

IS 15500 (Parts 1 to 8) :2004

All the amendments issued so far in the above specifications have been reviewed and incorporated whereverrequired in this standard.

On publication of this standard, the above Indian Standards would be withdrawn.

The formulation of amalgamated standard entailed the review of identification and packaging of handpumpcomponents covered in 1S 12732: 1989 ‘Nomenclature, identification and packaging of components for deepwellhandpumps’. It was felt that the packaging requirements should also be part of this amalgamated standard.Hence accordingly packaging requirements have also been included in this amalgamated standard. On publicationof this standard, IS 12732 would also be withdrawn.

It is expected that publication of the amalgamated document would facilitate all the concerned organizationsinvolved in development, manufacture, inspection, installation and maintenance activities, ultimately improvingthe availability of safe drinking water to communities.

For the purpose of deciding whether a particular requirement of this standard is complied with, the final valueobserved or calculated, expressing the resu It of a test or analysis shall be rounded off in accordance withIS 2:1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained in therounded off value should be same as that of the specified value in this standard.
