x1 is a pump/injector [tool/apparatus] pumping/inserting fluid x2 to x3 from x4 by means x5.

x2 fluid may be liquid or gas; x5 may be a force; a pump generally causes a pressure gradient, such that x3 is a place of lower pressure, x4 a place of higher pressure. (cf. gapci, litki, rinci; metaphorical use of fepri for gas, risna for liquid, rinci, tutci)

In notes:

fepri
x1 is a/the lung [body-part] of x2; [metaphor: breathing/respiratory apparatus/bellows].
gapci
x1 is gaseous/fumes/a gas/vapor of material/composition including x2, under conditions x3.
litki
x1 is liquid/fluid, of composition/material including x2, under conditions x3.
rinci
x1 liquid/fluid drains/strains/flushes from source x2 through drain/strainer x3 by force x4.
risna
x1 is a/the heart [body-part] of x2; [emotional/shape metaphors are NOT culturally neutral].
tutci
x1 is a tool/utensil/resource/instrument/implement used for doing x2; [form determines function].
fletu'u
x1=t1 is a pipe/tube/hose carrying fluid x2=f2=t3 towards x3=f3 from x4=f4 (direction/source)
sakcpa
c1 sucks (gets by sucking) c2=s2 from c3=s3
varmuvmi'i
mi1 is a fan for moving air to destination mu2 from origin mu3 over path/route mu4.
