English translation:No. of plungers (no. of cylinders)

Explanation:
There are many types of plunger pumps….Those with one, two, three, and multiple plungers (with cylinders). Plunger pumps are a type of reciprocating pump. (Please see websites below.

連 is a series counter, or it is about a "set."...
In this case it is the number of cylinders/plungers in the pump. (1,2,3, etc. - also called "simplex, duplex, triplex, etc. or 一連式二連式三連式など)

http://en.wikipedia.org/wiki/Pump
Reciprocating-type pumps require a system of suction and discharge valves to ensure that the fluid moves in a positive direction. Pumps in this category range from having "simplex" one cylinder, to in some cases "quad" four cylinders or more. Most reciprocating-type pumps are "duplex" (two) or "triplex" (three) cylinder.
Typical reciprocating pumps are plunger pumps, diaphragm pumps
A plunger pump consists of a cylinder with a reciprocating plunger in it. The suction and discharge valves are mounted in the head of the cylinder. In the suction stroke the plunger retracts and the suction valves open causing suction of fluid into the cylinder. In the forward stroke the plunger pushes the liquid out of the discharge valve.

通常、動力噴霧機には、ピストン式、プランジャー式のいずれもクランク機構を使用するものが多く、シリンダ数によって、1連、2連、3連と呼ばれています

Kerr Pump manufactures simplex, duplex, triplex, quintuplex and sextuplex plunger and piston pumps for any application where liquids are moved under pressure.

http://www.dencilpumps.com/plunger-pump.htm
Plunger pumps are positive displacement pumps that" displace" a given amount of fluid on each cycle stroke of operation .The reciprocating motion of a plunger, with a ball check valves on each side of the pump body, creates the pumping action.
Pumps can be offered in simplex, duplex or multiple heads for handling different chemicals with common motor. Each head has independent connection and the capacity of head can also be independently adjustable. They can be single acting or double acting.
