## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA4547:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA4547:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

Make fountains or plant-watering projects with this submersible water pump. It's great for beginner projects and super easy to use! The pump is basically a DC motor that is powered with 3V and draws 100mA. When powered, the pump sucks water in from the side of the plastic casing and pushes it out the tubing port. The pump must be primed by keeping it inside water at all times. Reversing the polarity does not turn it into a suction device, it will only pump water!

This isn't for use with drinking water! Adafruit don't have longevity rating for this pump, Adafruit have run it for a week and it seems OK but Adafruit would not recommend it for long term installations. It's best used by students and artists who want something simple and inexpensive.

You can PWM the motor to speed up or slow down the flow rate. Works great with either a power transistor (basic on/off) or a motor driver chip such as the L293D. [If you need a self-priming / food-safe / reversible direction pump, check out Adafruit's peristaltic pumps](https://core-electronics.com.au/search/?q=peristaltic)!

**Please note**: This is ***just*** the pump and power wires. Silicone tube is not included, so why not grab [this 1 meter long PVC tubing](https://core-electronics.com.au/tubing-for-submersible-pumps-pvc-8mm-id-1-meter-long.html) while you're here?

We also carry this pump [in a horizontal style](https://core-electronics.com.au/submersible-3v-dc-water-pump-horizontal-type.html).

## Technical Details

- Wire length: ~23cm
- Pump body: 45mm long
