You can make a very efficient pump using a PVC pipe, cycle spoke, nut, rubber tube and other odd materials. Make a 1-cm diameter hole in the lid of a film can. Also make a big hole in the base of the bottle to press fit a PVC pipe. Take a 3-cm long tape. Stick 1-cm on itself. The doubled part will have no glue. Fix the sticky part inside the lid to make a flap – the SUCTION VALVE. The valve will open and close. 
Press fit a 30-cm long PVC pipe in the base of the bottle. Fix the lid with the Suction Valve. This would be the Cylinder & Suction-Valve Assembly. 
Place a tooth paste lid in a cycle spoke. Then sandwich a circle of rubber between two washers and nuts. The rubber circle will act like a good piston. This would be the Con-rod & Piston Assembly.
Make a small hole in the PVC pipe for the water to exit. This would be the Delivery Port. 
Place the Piston and Con-rod in the PVC pipe cylinder. Then fix the toothpaste lid in the pipe and seal it with glue. 
The Pump is almost ready for action. 
Place the pump in a bucket of water and move the bicycle spoke up and down. On the up stroke very large quantities of water will gush out. This pump can throw water 5-metres away.
