Integrated mixing pump
A mixing pump includes a power cylinder and a second cylinder wherein one of the power cylinder and the second cylinder is interchangeable between single and double acting and wherein a working fluid is supplied to the power cylinder under pressure.
1 . A mixing pump comprising:
a power cylinder; and
a second cylinder;
wherein one of the power cylinder and the second cylinder is interchangeable between single and double acting;
wherein a working fluid is supplied to the power cylinder under pressure.
2 . The mixing pump of claim 1 , wherein the power cylinder includes a biasing mechanism.
3 . The mixing pump of claim 1 , further comprising a third cylinder.
4 . The mixing pump of claim 1 , wherein one of the working fluid and an additive fluid is supplied to the second cylinder.
5 . The mixing pump of claim 4 , wherein the additive fluid is at least one of glycol and control system concentrate.
6 . The mixing pump of claim 1 , further comprising a fluid selector valve coupled to the second cylinder.
7 . The mixing pump of claim 1 , further comprising a switch valve to alternately direct the working fluid between a first chamber and a second chamber of the power cylinder.
8 . A mixing pump comprising:
a power cylinder;
a second cylinder; and
a third cylinder;
wherein a working fluid is supplied to the power cylinder under pressure.
9 . The mixing pump of claim 8 , wherein at least one of the power cylinder, the second cylinder, and the third cylinder is interchangeable between single and double acting.
10 . The mixing pump of claim 8 , wherein at least one of the working fluid and an additive fluid is supplied to at least one of the second cylinder and the third cylinder.
11 . The mixing pump of claim 10 , wherein the additive fluid is at least one of glycol and control system concentrate.
12 . The mixing pump of claim 8 , wherein the working fluid is potable water.
13 . The mixing pump of claim 8 , further comprising a switch valve to alternately direct the working fluid between a first chamber and a second chamber of the power cylinder.
14 . A mixing pump comprising:
a first cylinder, a second cylinder, and a piston assembly;
a first piston of the piston assembly dividing the first cylinder into a first chamber and a second chamber;
a second piston of the piston assembly dividing the second cylinder into a third chamber and a fourth chamber, wherein the second piston is displaced by the first piston;
a pressurized working fluid connected to a switching mechanism, wherein the switching mechanism is configured to alternately communicate the pressurized working fluid between the first and second chambers of the first cylinder to displace the first piston; and
a first additive fluid connected to an inlet of one of the third and the fourth chambers of the second cylinder;
wherein the pressurized working fluid and the additive fluid are outputted to a supply tank as the piston assembly reciprocates within the first and second cylinders.
15 . The mixing pump of claim 14 , wherein the first and second cylinders are sized to output a specified ratio of the pressurized working fluid and the first additive fluid.
16 . The mixing pump of claim 14 , wherein a second additive fluid is connected to an inlet of the other of the third and fourth chambers of the second cylinder.
17 . The mixing pump of claim 16 , wherein the first and second cylinders are sized to output a specified ratio of the pressurized working fluid, the first additive fluid, and the second additive fluid.
18 . The mixing pump of claim 14 , wherein the first additive fluid is connected to an inlet of the other of the third and fourth chambers of the second cylinder.
19 . The mixing pump of claim 14 , further comprising:
a third cylinder;
a third piston of the piston assembly dividing the third cylinder into a fifth chamber and a sixth chamber, wherein the third piston is displaced by the first piston; and
a second additive fluid connected to an inlet of at least one of the fifth and sixth chambers of the third cylinder.
20 . The mixing pump of claim 19 , wherein the first, second, and third cylinders are sized to output a specified ratio of the pressurized working fluid, the first additive fluid, and the second additive fluid.
21 . The mixing pump of claim 14 , wherein the pressurized working fluid is switchably connected to an inlet of at least one of the third and fourth chambers of the second cylinder.
