Handpump SS-Riser 32ND (Product Code: SLE/PRP/04) is a 3-metre stainless steel riser pipe of 32 mm nominal diameter, paired with one stainless steel connecting rod, used to build the rising main and rod string of a hand pump installed in a borehole or well. Drilling contractors and water-supply programmes order it length by length, because every riser pipe comes with its own 10.8 mm diameter rod. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

In a lever-type hand pump, the riser pipes form the column that carries water from the cylinder up to the pump head, while the connecting rods inside that column transfer the handle's up-and-down movement to the piston. The Handpump SS-Riser 32ND provides both parts in matching 3-metre lengths, so the installer screws one pipe onto the coupling of the last and joins the rods through their M12 threads as the string is lowered.
Keep the HDPE thread protectors in place until each pipe is about to be joined, because damaged threads are a common cause of leaking joints. Lay pipes and rods on clean supports rather than bare ground during installation, and count the lengths against the planned cylinder depth before the crew goes to site.
These stainless steel riser sets are supplied by Jain Scientific Equipments Private Limited, the company behind the ScienceLab name, from Ambala in Haryana, India. The company sources rising-main components and other water-point hardware for contractors, NGOs, schools and institutional buyers, and co-ordinates quotations and dispatch within India and to international markets. More about the company is on the ScienceLab profile page.

What comes with each Handpump SS-Riser 32ND?
Each Handpump SS-Riser 32ND consists of one 3-metre stainless steel riser pipe of 32 mm nominal diameter, with a female threaded coupling on one end and an HDPE thread protector on the other, plus one 3-metre stainless steel 304 connecting rod of 10.8 mm diameter.
What thread does the Handpump SS-Riser 32ND connecting rod use?
The connecting rod of the Handpump SS-Riser 32ND has an M12 rolled male thread at one end and an M12 stainless steel female threaded coupling welded at the other, so successive rods screw directly into one another as the rod string is assembled.
How many Handpump SS-Riser 32ND sets does a borehole need?
The number of Handpump SS-Riser 32ND sets equals the cylinder setting depth divided by 3 metres, rounded up, because each set adds one 3-metre pipe and one 3-metre rod. Confirm the final count against the pump maker's installation drawing for that borehole.
Does the Handpump SS-Riser 32ND fit the Handpump Variant 3 Norm?
Not as described: the Handpump SS-Riser 32ND is a 32 mm nominal-diameter riser, while the Handpump Variant 3 Norm is described for a larger riser pipe size. Tell us the pump model you are using through the contact page and we will check which riser set applies.
Why are the Handpump SS-Riser 32ND pipe and rod made of stainless steel?
Stainless steel is widely used for hand pump riser pipes and rods such as the Handpump SS-Riser 32ND because it resists corrosion in groundwater better than plain steel, which helps keep water clear of rust and reduces how often below-ground parts need replacing.
Who supplies the Handpump SS-Riser 32ND?
The Handpump SS-Riser 32ND is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, which sources the riser sets and quotes them for project, institutional and export buyers. Send quantities and delivery details through the contact page or the enquiry cart.
