The pump radial-piston unregulated 50nr4

Pumps of radial-piston-piston unregulated series 50 rubles and sectional series 50NS

Direct-piston-piston-piston-piston unregulated type 50 HP and sectional type 50 ns with a fluid flow constant in size and direction is intended for general domestic construction use in hydraulic drives that meet the requirements of GOST 17411-91.

Pumps 50HR provides one or two fluxes of working fluid with pressure up to 50 MPa,
And the pumps of 50NS, in addition, another supply from the plate pump up to 2.5 MPa.

The pumps are designed to work on mineral oils with a viscosity of 21 to 265 mm2/s (SST) at an oil temperature from +10 to -50 ° C and ambient temperature from 0 to +50 ° C.

Recommended working fluids-Mineral oils of the NPI NP-40z GOST 16728-78, IGP-30, IGP-38 and IGP-49 to TU 38.101413-97.
Nominal subtlety of oil filtration:
40 μm - for pumps of type 50);
25 μm - for pumps type 50NS.

The class of purity of working fluid 14 according to GOST 17216-71.

The direction of rotation of the pump shaft is right (clockwise, if you look from the sock of the shaft). Pumps can be made of left rotation. The position of the pumps during operation is horizontal or vertical (the toe of the shaft up). Pumps with a working volume of 500 cm3 work only in a horizontal position.

Example designation when ordering:

Sectional pump with working volumes:
Pedagogical piston - 32 cm3;
plate - 12.5 cm3,
With nominal pressure:
radial -piston - 50 MPa;
plate - 2.5 MPa,
left rotation, execution of UHL4:
50NS 32 l

The same submersible overalls:
50NS 32 l on4

The same two -axle with a working volume:
50NS 32/2 l on4

A radial-piston pump with a working volume of 500 cm3, with a nominal pressure of 50 MPa, performance on paws, right-winging, execution of UHL4:
