Water Pump Accessories: What Runs the Pump, What Protects It and What Is Optional

Water pump accessories are the parts around a pump that carry its power, guard its motor, decide when it switches on and keep water moving in one direction. A pump bought alone may run unprotected, overflow the tank or hammer its own pipe. This page sorts ToolHaat accessories by the job each does, so you know what your setup needs. For the pumps themselves, start at Water Pumps and Motors.

Every accessory does one of three jobs, and the job tells you how urgent it is.

JobTypical partsHow to treat it
Makes the pump runControl panel or starter, submersible cableRequired. Without a matching one the pump cannot start safely
Protects the pumpOverload relay, non-return valve, dry run protection, pressure switchStrongly advised. Skipping them shows up later as a burnt winding or a split pipe
Saves effortTank alarm, level controller, pressure gauge, strainerOptional, though worth having where the tank is out of sight

Submersible Pump Control Panel and Starter: Matching the Motor

A panel or starter must match the motor's phase, HP and current, and every other choice follows from that. On single phase submersibles the panel also carries the running capacitor, and the product name states its value. CROMPOWER metal body panels list 36, 50 and 72 MFD for 1 HP, 1.5 HP and 2 HP oil filled pumps, while ENJOY V4 relay panels for 3 HP and 5 HP list 50+50 and 72+72 µF. The capacitor belongs to the motor design, so match the panel to the pump nameplate and not to HP alone.

For three phase pumps, a DOL starter is named by its amp range. ENJOY lists 6 to 10 A for 0.25 to 0.75 HP, 9 to 14 A for 1 HP, 13 to 21 A for 1.5 to 2 HP and 20 to 32 A for 3 HP and above. Read the full load current on the motor nameplate, pick the range that contains it, and set the overload relay to that nameplate figure. The ENJOY 5 HP three phase relay control panel shows the pattern: HP, relay range and pump type in one line. A bigger set might use the Crompton 13-22 A DOL starter, listed for a 10 HP motor and a 7.5 HP submersible.

Isolate the supply before opening any panel, earth the body, and have a qualified electrician do the wiring. Not sure which amp range fits? Send the nameplate current through the Request for Quote form.

Submersible Cable: Thickness and Length

Submersible cable must be thick enough for the whole run, because a long thin cable loses voltage before it reaches the motor. A motor that receives less than its rated voltage draws more current and runs hot, a real risk where farm supply already swings. As a rule of thumb, a longer run or a bigger motor needs a thicker conductor, and between two sizes you take the thicker.

The listing names show the pairing the makers suggest:

  • CROMPOWER 1.5 sq mm, 30 m, for pumps up to 1 HP, and a 30 m listing for 1.5 HP and 2 HP
  • KBS 2.5 sq mm in 30, 50 and 70 m for 2 HP and 3 HP pumps
  • KSB 4 sq mm in 50, 70 and 100 m for 5 HP and 7.5 HP pumps
  • KSB 6 sq mm in 50, 70 and 100 m for pumps above 10 HP

Measure the full length, which is the depth where the pump hangs plus the run from the borewell to the panel. Then check the maker's cable chart, since size depends on current as well as length. The Havells and KEI wires in the category are listed for house wiring, so keep them on the building side and use flat submersible cable for the part that goes into the water.

Non-Return Valve: Size, Material and Position

A non-return valve (NRV) stops water running back down the delivery pipe when the pump stops. Without one on a deep or long line, the pipe drains and the returning water can spin the pump backwards or shock the pipe.

Fit the first valve close to the pump and below the water level, preferably a spring-loaded type, since swing valves close slowly. Very deep lines often add more valves, so follow the pump maker's manual. ToolHaat lists vertical NRVs from 1/2 inch (15 mm) to 2 inch (50 mm), in brass and in SS-304 and SS-316 stainless steel.

  • Match the valve size to the delivery pipe
  • Follow the flow arrow on the body
  • SS-316 is generally the more corrosion resistant grade, so confirm the grade for salty or treated water

Water Level Controllers, Alarms and Float Switches

An alarm only warns you, while a controller switches the pump for you. Use these decision rules.

  • If you only need a warning, choose a tank overflow alarm. SensaSwitch and SSMAQUAMAX list battery operated versions
  • If you want the pump to stop when the tank fills but start by hand, choose a semi automatic controller such as the Vahra semi automatic water level controller
  • If you want start and stop both automatic, choose a fully automatic controller
  • If the water sits in an underground tank, look for controllers named reverse or for underground tanks
  • If there is no power at the tank, the MSR level control valve works without electricity

Check what current a controller can switch. Names such as 0 to 1.5 HP pumps or 30 A relay set a limit, and larger pumps should be switched through a contactor or starter. Some controllers mention dry run protection, so read the product page to see what they sense.

For sumps and drains, a float switch does the same job. The heavy duty 2 m float switch for sewage pump is one example, and the matching pumps sit under dewatering and sewage pumps.

Pressure Tanks, Pressure Switches and Gauges

Add a pressure tank only when your line is pressurised, because its job is to hold a reserve so the pump does not start at every tap. A pump controller is the tank-free alternative; check its pressure rating on the listing. ToolHaat lists tanks of 2, 8, 24, 35 and 60 litres, some rated to 10 bar, along with a Danfoss KP35 pressure switch, Crompton and BTALI pump controllers and analog gauges.

A gauge helps you tell a weak pump from a blocked pipe. For poor pressure in bathrooms, see booster pumps first.

Before the First Start: A Short Checklist

Most accessory failures are matching errors, so run these checks first.

  • Compare the relay or overload setting with the full load current on the nameplate
  • Confirm the NRV arrow points along the flow, away from the pump
  • Check the cable reaches the panel with slack and the body is earthed
  • Place level sensors at the heights you want for start and stop
  • Before summer, when the water table falls, test any dry run protection

FAQs related to Pump Accessories

What accessories do I need for a submersible pump?

+

At minimum you need a control panel or starter that matches the motor and a submersible cable long enough for the setting depth. A non-return valve on the delivery line is strongly advised, and a level controller or tank alarm is optional but useful. Match each part to the pump nameplate and not to HP alone.

Which starter should I buy for a 5 HP three phase pump?

+

Choose the DOL starter whose amp range contains the full load current printed on the motor nameplate, then set the overload relay to that figure. HP alone is not enough, because different motors of the same HP can draw different current. Listings state the HP and amp range in the name, so compare both.

What is the use of a non-return valve in a borewell pump line?

+

It stops water flowing back down the delivery pipe when the pump switches off. That keeps the line full, avoids the pump restarting against an empty pipe and reduces the risk of backward spinning or a pressure shock. Fit it close to the pump, below the water level, and match its size to the delivery pipe.

How do I choose the right submersible cable thickness?

+

Add the depth at which the pump hangs to the run from the borewell to the panel, then pick a cable thick enough for that total length and the motor current. Longer runs and bigger motors need thicker cable. Check the maker's cable chart, and choose the thicker size if you fall between two.

Can I use a water level controller with a 3 HP pump?

+

Only if the controller is built for that load. Many controllers state a limit such as 0 to 1.5 HP or a relay current, and larger pumps should be switched through a contactor or starter. Read the product page, and ask for help through the Request for Quote form if the rating is unclear.

How do I stop my overhead tank from overflowing?

+

The simplest fix is a tank overflow alarm that sounds when the water reaches the sensor. For a hands-off fix, use a water level controller that switches the pump off when the tank is full, or a level control valve that works without electricity. Pick based on how often you can check the tank.

Is a pressure tank or a pump controller better for a home pressure system?

+

Neither wins in every home. A pressure tank holds a reserve of water under pressure so the pump does not start at every tap, which suits a pressurised line with many outlets. A pump controller starts and stops the pump on flow or pressure, and suits a few outlets where space is tight. Check the tank or controller details on the product page, and see the booster pump category for the pump itself.

Can I buy pump accessories in bulk with a GST invoice?

+

Yes. Every ToolHaat order carries a GST invoice, and bulk and tiered pricing is shown on each product page with the minimum order quantity. For dealer stock or project orders, you can send the pump details and the quantity you need through the Request for Quote form.
